Solar panels harness the power of the sun to generate electricity through a process called the photovoltaic effect. Each panel consists of multiple solar cells made of semiconductor materials, usually silicon. When sunlight hits these cells, it excites electrons, creating an electric current. This d

The internet has transformed the way humans communicate, work, and access information. It began as a military project in the 1960s called ARPANET, designed to allow computers to share data over long distances. Over time, this network expanded and evolved, leading to the birth of the World Wide Web i

The human brain is one of the most complex and powerful organs in the body, capable of processing vast amounts of information every second. It consists of billions of neurons that communicate through electrical and chemical signals, allowing us to think, feel, and make decisions. Despite its small s

Rainbows are a beautiful natural phenomenon that occurs when sunlight passes through water droplets in the air. This process, known as refraction, causes the light to bend and separate into different colors. The light then reflects off the inside surface of the droplet and refracts again as it exits
