Refraction of Light

प्रकाश का अपवर्तन

In Class 12 Physics, this topic explains how light changes direction when it passes obliquely from one transparent medium to another because its speed changes. Students learn the laws of refraction, Snell’s law, refractive index, and the relationship between speed, wavelength, and frequency in different media. The topic also develops understanding of apparent depth, refraction through glass slabs and prisms, and total internal reflection, connecting these ideas with ray optics and optical instruments.
