Notes from the JEE Toppers

1 : Reflection and Refraction
  • Understand the laws of reflection and refraction thoroughly.
  • Use Snell’s Law for refraction: (n1sinθ1=n2sinθ2).
  • 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.
