Chapter 16: Light
Key Laws:
• Angle of incidence = Angle of reflection
• Incident ray, reflected ray, and normal lie in same plane
• 1/v + 1/u = 1/f (mirror formula)
Q1. A ray of light strikes a plane mirror at 30° to the normal. Find the angle of reflection.
SolutionAngle of reflection = Angle of incidence = 30°
Q2. What is the lens formula?
