Assertion: The edges of the images of white object formed by a concave mirror on the screen appear white. Reason: Concave mirror does not suffer from chromatic aberration.
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion.
- BIf both assertion and reason are true but reason is not the correct explanation of assertion.
- CIf assertion is true but reason is false.
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion.
Step-by-step solution
The rays of all colours incident on a concave mirror at the same angle are reflected at the same angle. As there is no chromatic aberration, the reflected image is white.
