Question

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

Answer 1

Explanation:

we know that ,

the Engle of incident= angle of reflection

due to this the angle of reflection is 25° .

two laws of reflection:

1). the angle of incident is always equal to the angle of reflection.

2). the incident Ray , reflected Ray and normal all are lie on same point of a plane

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.
