In todayтАЩs world, most adolescents start using social media before they are 13 years old. Platforms like Instagram, WhatsApp, YouTube and TikTok have become part of their daily routine.
Many surveys from health and government agencies show that teenagers spend between 3 to 5 hours every day on social media. For example, in some studies, more than 90% of teenagers said they use social media daily, and around half said they are online тАЬalmost all the time.тАЭ This huge increase in use has changed how adolescents think, feel and behave in their everyday life.
2. Hidden Negative Impact of Social Media
Social media looks enjoyable, but its overall effect on adolescents can be harmful when it is used without limits. Many research studies show a link between heavy social media use and problems like stress, anxiety and low confidence. Young people may feel pressure to reply quickly, stay active and keep posting to maintain their online image. This pressure makes them restless and worried, even when they are not using their phone. Slowly, social media starts controlling their mood, behaviour and decisions instead of supporting them.
3. Physical Health, Eye Problems and Screen Time
Long hours on mobile screens reduce physical movement and harm the body. Instead of playing outside, many adolescents sit for hours scrolling through reels and videos. This sitting habit increases the risk of weight gain, body pain and poor posture. Continuous screen use also causes eye strain, headaches, dryness and blurred vision, a problem many students complain about after online classes and late-night mobile use. When screen time becomes more than 2 to 3 hours a day for entertainment, it clearly starts affecting physical health.
4. Mental Health, Depression and Anxiety
Social media can strongly affect the mind of a growing child. Many studies suggest that heavy social media use is connected with more cases of depression, anxiety, loneliness and mood changes in adolescents. For example, a teenager who keeps seeing happy, filtered photos of others may feel that their own life is boring or a failure. Cyberbullying, negative comments and trolling can hurt self-respect and create deep emotional wounds. In serious cases, constant online negativity can lead to self-harm thoughts, isolation and a complete loss of interest in real life activities
.5. Sleep Loss, Less Study and Poor Concentration
Late-night mobile use is now a common habit among adolescents. They promise themselves тАЬjust five more minutesтАЭ but spend hours watching reels or chatting with friends. The bright screen and exciting content keep the brain active, so sleep is delayed and becomes shallow and disturbed. Due to less sleep, students feel tired in class, cannot focus, forget what they learn and perform poorly in exams. Less study, less concentration and more screen time create a dangerous cycle that directly affects their future.
6. Time, Money and Addictive Algorithms
Social media platforms use powerful algorithms that study what users like, watch and share. Based on previous reels and videos, the next reel is carefully selected to keep the user watching for a longer time. As a result, a teenager plans to watch only one video and suddenly realises that one hour has passed. Along with time, they also waste money on mobile data, inтАСapp purchases and products shown in ads that they do not really need. Social media slowly becomes like a digital trap that catches their attention and does not easily let it go.
7. Family Relations and Real-World Social Skills
When adolescents spend more time in the virtual world, they automatically spend less time with family. A common scene in many homes is that everyone is together, but each person is busy on their own phone. Conversations during dinner or family time are replaced by silent scrolling and quick replies. Young people also lose the habit of making eye contact and having deep face-to-face conversations. Over time, this reduces emotional bonding in the family and creates distance between parents and children.
8. Privacy, Oversharing and Unnecessary Information
Many adolescents share photos, videos, locations and personal details without understanding the long-term risk. They may post their school name, daily routine or family information for fun or likes. This unnecessary information can be misused by strangers, fake accounts or cybercriminals. Once something is uploaded, it is very difficult to remove it completely from the internet. Without proper guidance, young users can lose control over their own privacy and digital identity.
9. Less Sports, Outdoor Play and Community Life
As mobile use increases, time for sports and outdoor play naturally decreases. Instead of playing football or cricket on the ground, many teenagers now prefer playing online games or watching sports clips. This reduces their fitness, energy levels and ability to work in a team. They also miss festivals, cultural programmes and community events which develop confidence and social responsibility. A child who spends most of the time in a room with a phone cannot fully learn how to live in a real society.
10. Towards Balanced and Healthy Use
The solution is not to completely ban social media, but to use it in a limited and meaningful way. Parents and teachers can help adolescents fix clear rules, like no phones during meals, study time and after a certain night time. Families can create a simple тАЬdigital agreementтАЭ that includes daily screen limits, privacy rules and time for sports, hobbies and reading. Adolescents should also learn how social media works, why they see certain reels and how to say тАЬstopтАЭ and close the app when needed. By using social media carefully, they can protect their health, save time and money, and build a stronger, happier real life beyond the screen.

Electromagnetic Field Engineering is an important subject in Electronics and Communication. It mainly deals with electric fields and magnetic fields, which are invisible but exist everywhere around us. These fields help us send information from one place to another. Today, when communication is a daily need, understanding electromagnetic fields becomes very important.
Communication plays a big role in human life. We talk through mobile phones, use internet, watch television, listen to radio and send messages instantly. All this happens because electromagnetic waves carry signals. Without these waves, communication cannot work. That is why Electromagnetic Field Engineering is the basic foundation of communication engineering.
The subject begins with simple concepts like scalar and vector. A scalar has only value, like temperature or time. A vector has value and direction, like force or velocity. We study vectors because electric and magnetic fields always have direction. Knowing this helps us understand how fields move and interact.
Next, we learn about coordinate systems. They help us find the position of points in space. There are mainly three types тАФ Cartesian, Cylindrical and Spherical. Each one is useful in different situations. For example, spherical system is helpful while studying antennas, and cylindrical system helps in understanding wires and cables.
The subject also includes some basic laws, known as electromagnetic theorems. Important ones are Gauss Law, FaradayтАЩs Law and AmpereтАЩs Law. These laws tell us how electric charge behaves, how magnetic fields are generated and how electricity and magnetism are linked. They help students relate theory to real life behaviour of fields.
Electric Field Intensity and Magnetic Field Intensity are two key topics. Electric intensity explains how strong an electric field is. Magnetic intensity shows the strength of a magnetic field. Both are related to each other and are useful for understanding how waves travel through air or space.
One of the most important parts of the subject is MaxwellтАЩs Equations. These equations combine electricity and magnetism into one complete theory. They help us understand how electromagnetic waves are created and how they move. MaxwellтАЩs equations are the heart of communication technology used worldwide.
Transmission lines are also studied in this subject. These are long cables that carry signals from one end to another. They are used in telephones, internet cables, television broadcast lines and other connections. Without learning transmission lines, designing communication systems becomes very difficult.
Electromagnetic field engineering has many applications in real life. It is used in radar, satellite communication, wireless networks, microwave links, GPS, and many modern devices. Even some medical machines like MRI scanners work on electromagnetic principles. This shows how useful and powerful the subject is.
Although it sounds technical, its use is very simple in real life. Every call we make, each video we watch online, every message we send тАФ all are possible only because of electromagnetic waves. We enjoy fast communication daily without seeing the science behind it.
In the end, Electromagnetic Field Engineering is not just a subject for students. It is the foundation of the entire communication world. Without it, wireless communication would not exist. It helps us stay connected across cities, countries and continents. Truly, one cannot imagine communication engineering without electromagnetic field engineering.
Artificial Intelligence (AI) is the branch of computer science that enables machines to perform tasks that normally require human intelligence. The term тАЬArtificial IntelligenceтАЭ was introduced by John McCarthy in 1956 during the Dartmouth Conference. Since then, AI has evolved from a research idea into a major part of modern life.Today, it powers the systems we use daily тАФ from phones to hospitals, from factories to classrooms.
1. Understanding Artificial Intelligence
AI means creating machines that can think, learn, and act like humans. It allows computers to analyze data, recognize patterns, and make decisions automatically. In simple words, AI helps machines тАЬlearnтАЭ from experience, just like people do.
Types of AI
AI can be categorized in two main ways тАФ by capability and by functionality.
By Capability:
