Notes from the JEE Toppers
1 : Reflection and Refraction
- Understand the laws of reflection and refraction thoroughly.
- Use Snell’s Law for refraction: $$(n_1\sin\theta_1 = n_2\sin\theta_2).$$
- Remember the sign conventions for angles (e.g., angles measured clockwise are negative).
- Practice problems involving plane mirrors, spherical mirrors, and lenses to grasp image formation.
