 Optics. It's learning the rules of how light bounces, bends, spreads, mixes. But why study that? Because we can use it to unravel the wonders of rainbows, the mysteries of soap bubble colors, figure out how lenses sharpen our vision and how fiber optics connects us across the globe. Excited about learning all these? Well, we have a course for you. This course covers the main topics of Class 12 CBC, Geometrical and Wave Optics. But the beauty is every unit is centered around a big question. For example, the first unit is about convex and concave mirrors. But the big question is why are objects closer in some mirrors than others? Similarly, unit 2 is about lenses. But why study that? Because it helps us understand how telescopes and microscopes work. So almost everything you learn is used to answer some big relevant questions so that you don't feel like you're just studying for the sake of the exams, but you feel like you're actually understanding how nature works. Finally, every unit has videos, exercises for you to practice quizzes, and finally unit tests to give you everything needed to master all the essential topics. Together, let's explore the wonders of the colorful world around us. I'll see you inside.
