Question

A ray of light falling on a mirror makes an angle of 25° with
the mirror. What is the angle of reflection ? State the two laws
of reflection.​

Answer 1

Explanation:

➝ A ray of light falling on a mirror makes an angle of 25° with the mirror. What is the angle of reflection.

↪ Angle between the incident ray and mirror = 25°

↪ Angle between normal and mirror = 90°

↪ Angle between incident ray and normal = 90° - 25°

↪ Angle of reflection =  65°

➝ State the two laws of reflection.

↪ The reflected Ray, and the normal, all lie in the same plane.

↪ Angle of reflection is always equal to the angle of incidence.

Answer 2

QUESTION-

Laws of refection.

ANSWER-

The first law of reflection is related the rays of light i.e incident ray and reflected ray

The incident ray, the reflected ray as well as the normal to the mirror's surface lie in the same plane.

The second law of reflection is related to the angles the rays make with the surface of the object.

The $\angle i= \angle r$with respect to the normal of the surface of the mirror.
