Question

if an incident ray makes an angle of 40 degree with the normal, what will be the angle between the reflected ray and the normal . explain with process ​

Answer 1

Answer:

40°

Explanation:

as reflected and incident ray value are same

Answer 2

Answer:

Explanation:

If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. Then the angle of reflection will 50 degree ( angle of incidence = angle of reflection). 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.
