Question

When the angle between incident ray and mirror is increased. What will be the effect on angle of reflection?

• A. It will decrease
• B. It will increase
• C. It will remain constant
• D. Can't be predicted

Answer 1

The correct option is A It will decrease

If the angle between the mirror and the incident ray increases, the angle of incidence will decrease accordingly.
And if angle of incidence will decrease, angle of reflection will also decrease.
As we know from laws of reflection, angle of incidence is equal to angle of reflection.
