Question

If the angle between an incident ray and a reflected ray is 44°, then double of angle between the reflectd ray and the normal on the reflecting surface will be:
(1) 22°
(2) 44°
(3) 66°
(4) 88°

Answer 1

44° is the ans. because angle form by a reflected and an incident ray is divided equally in two parts by normal so if we take it separately , then the angle of reflection is 22 and its twice is 44
