Question

The first law of reflection states that :

• A. The incident ray, the reflected and the normal at the point of incidence all lie in the same plane.
• B. The angle of incidence is always equal to the angle of reflection.
• C. The angle of incidence is always equal to the angle of reflection only when the mirror is kept at an angle of 45^o.
• D. The angle of incidence is sometimes equal to the angle of reflection.

Answer 1

The correct option is (A) The angle of incidence is always equal to the angle of reflection.

According to the first law of reflection when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
