Question

An incident ray on a plane mirror is reflected in a direction such that the angle between the incident and the reflected rays is 75°.What is:

a.the angle of reflection ?
b.the angle of refraction ?​

Answer 1

Answer:

75/2

=37.5

Explanation:

As angle of incident = angle of reflection

75= angle of incident + reflection

we know incident = reflection

so 75=2 x

x=75/2=37.5
