Question
As the angle of incidence decreases, the angle made by the reflected ray with the normal _______.
- Decreases
- Remains the same
- Increases
- Changes irregularly
Hint:
The sum of the glancing angle and incident angle is 90 degrees.
The correct answer is: Increases
The angle between the incident ray and the mirror is called the glancing incidence angle.
now,
glancing incidence angle + incidence angle = 90 degrees
Therefore, as the glancing incident angle increases, the incident angle decreases.
Here the glancing angle is decreasing the incident angle will increase.
