Question

Which of the following are measured from the normal drawn at incident point?
(i) Angle of incidence
(ii) Angle of reflection

A:only (i)
B:only (ii)
C: both (i) and (ii)
D:None

​

Answer 1

Answer:

angles of reflection (option A)

Answer 2

C: Both (i) and (ii)

ExPlanation:

When we have the normal and incident point, then we can easily find the angle of incidence but we are also aware about the property that, angle of incidence = angle of reflection, i.e, ∠i = ∠r.

Therefore, with the help of normal and incident point we can find both Angle of incidence as well as Angle of reflection.
