LAW OF REFLECTION

  • The Law of Reflection states that the angle of incedence is equal to thr angle of reflection.

A ray of light strikes a surface and is reflected such that the angle between the incident ray and the reflected ray is 30°

(a) What is the angle of incidence?

  • Answer: 15°

(b) What is the angle of reflection?

  • Answer: 15°

Why?

  • The angle between the two rays is 30°, the perpendicular cuts the angle into half. That means, the two angles (15°) of the two rays (Incident and Reflected) are equal.
