Question

if an incident ray makesand angle of 40 with the normals, what will be the angle between the reflected ray and the normal?​

Answer 1

Answer:

If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. ... The angle between the incident ray and the reflected ray will be the sum of angle of incidence and the angle of reflection. Thus 50 degree + 50 degree = 100 degree.
