Question

Numerical: [2+2+1]

a. If the angle between the mirror and the incident ray is 45°, then what is the

angle between incident ray and reflected ray?

b. If the angle between incident ray and reflected ray is 90°, what is the angle of

incidence?

c. What is the angle of reflection in case of normal incidence?​

Answer 1

ANSWER

When an incident ray strikes normally to any reflecting surface then the reflected ray will trace back the incident ray.

Hence angle between incident ray and reflected ray is 0

0

.

Answer 2

Answer:

a 90

b45

c=0

Explanation:

a. i=r

=90

b.angle of incident=45

c.i=r

=i=0

r=0
