The angle between an incident ray and the plane mirror is 30°. The total angle
between the incident ray and reflected ray will be
(a)30°
(b)60°
(c)90°
d) 120°​

Answer 1

Answer:

60

Explanation:

since angle of incidence and angle of reflection is equal so 30+30=60

Answer 2

Answer:

60

Explanation:

since angle of incidence and angle of reflection is equal to 30 +30 =60
