Question

A ray of light strikes a reflective plane surface at an angle of Y =49° with the plane surface (shown in the figure). find the following angles- Angle of incidence Angle of reflection angle of X​

Answer 1

Answer:

(a) The angle of incidence is 34°.

(b) The angle of reflection is 34°.

(c) The angle made by the reflected ray on the surface is 56°.

(d) The angle made by the incident ray and the reflected ray is 68°.

Explanation:

Referred to the attachment for the diagram.

a) Angle of incidence (i) = (90°-56°)

= 34°

So, the angle of incidence is 34°.

b) We know that angle of incidence is equal to the angle of reflection.

Hence, we get

Angle of reflection (r) = 34°.

c) Angle of reflection (r) = 34°.

So, the angle made by the reflected ray on the surface _

(90°-34°)

= 56°.

So, the angle made by the reflected ray on the surface is 56°.

d) Angle of incidence = 34°.

Angle of reflection = 34°.

The angle made by the incident ray and the reflected ray _

(34°+34°)

= 68°.

So, the angle made by the incident ray and the reflected ray is 68°.
