Question -
A concave mirror can converge a parallel beam of light to a point. The reflection taking place, in this case, is a regular reflection.
A concave mirror can converge a parallel beam of light to a point. The reflection taking place, in this case, is a regular reflection.
Answer: Option B
:
B
Regular reflection is a reflection in which all the incident parallel rays of lightremains parallelafter reflection from the reflecting surface. Incase of concave mirrors, the parallel beam of light is converged to apoint after reflection and hence ceases to be a parallel beam of light. Thus, the reflection is not regular, but an irregular one.
