Question

the diagram in Fig 4.18 shows an incident ray
AO and the reflected ray OB from a plane mirror.
The angle AOB is 30°. Draw normal on the plane
mirror at the point O and find :
(a) the angle of incidence
(b) the angle of reflection​

Answer 1

Answer:

1)75

2)75

Explanation:

So,

180(The straight angle) -30 = 150

Then

150/2=75

And as we know angle of incident and reflection are equal
