Question
As the angle of incidence decreases, the angle of reflection _______.
- Decreases
- Increases
- Remains the same
- Changes irregularly
Hint:
The angle between the incident ray and the mirror is called the glancing incidence angle.
The correct answer is: Decreases
The angle between the incident ray and the mirror is called the glancing incidence angle.
now,
Glancing incidence angle + incidence angle = 90
Therefore, as the glancing incident angle increases, the incident angle decreases.
Since the angle of incidence is equal to the angle of reflection, the smaller the angle of incidence, the smaller the angle of reflection.

An incident ray goes along the reflecting surface. The angle of reflection is ____ degrees.
When the angle along the reflecting surface , the incident ray is perpendicular to the reflecting surface. We know by the first law of reflection that angle of incidence is equal to angle of reflection . Here, the angle of incidence is 90 degrees so the angle of reflection will also be 90 degrees.
