Question:

The mirror used in search light is –

Solution:

Ans: (d)

A search light produces an intense parallel beam of light. This requires a reflector of large aperture. When a source is placed at the focus of a large concave mirror only the paraxial rays (not the marginal rays)are reflected as parallel beam, but when a source is placed at the focus of parabolic mirror all the rays are reflected  as an intense parallel beam.
