Q1. The angle of incidence is equal to the angle of reflection. This is the law of:
Answer: Reflection of light
Explanation: The first law of reflection states that the angle of incidence (measured from the normal to the reflecting surface) equals the angle of reflection, and both angles lie in the same plane. Refraction, diffraction, and total internal reflection are separate optical phenomena governed by different laws.
