Question
A light ray moving parallel to the principal axis of a concave mirror hits its surface. After reflection it _____.
- Passes through the focus
- Passes through the center of curvature
- Passes through the pole
- Goes along the incident ray
Hint:
Passes through the focus
The correct answer is: Passes through the focus
when the incident ray is parallel to the principal axis, the reflected ray passes through focus for a concave mirror.
