Question

A Ray of light is reflected from a plane mirror so that the angle between the incident and the reflected rays is 60° if the mirror is rotated to increase the angle of incidence by three degrees what will be the new angle between the incident and reflected rays​

Answer 1

Answer:

66

Explanation:

angle of incidence (i)+angle of reflection (r)=60

i=r

therefore let them be x

x+x=60

x=30

then angle is increased so angle of incidence =33

33+33=66
