Light – Reflection, Mirrors, Refraction & Numericals

Light is a form of energy that helps us see the world around us. From mirrors and lenses to rainbows and optical instruments, light plays a major role in daily life and science. Understanding how light travels, reflects, and bends is one of the most important foundations of physics.

In this detailed guide, we will understand reflection of light, spherical mirrors, refraction, lenses, image formation, human eye concepts, formulas, real-life examples, numericals, and important exam questions.
