Question
An incident ray passing through the focus of a concave mirror goes ____ after reflection.
- Along the normal
- Parallel to the principal axis
- Perpendicular to the principal axis
- None of the above
Hint:
Parallel to the principal axis
The correct answer is: Parallel to the principal axis
for a concave mirror, the reflected ray travels parallel to principal axis if the incident ray passes through focus.
