Question

(b) The angle between the incident ray and the
ray reflected from the plane mirror is 70%
"The angle of incidence will be
(i) 709
(ii) 30
a) 35
(iv) 90°
HOW???​

Answer 1

Answer:

let the angle of incidence be i and angle of reflection be r

i + r =70

r = i

i + i =70

2i = 70

i = 35 Ans
