Question

A dentist uses a concave mirror to send light into his patients mouths. If a parallel beam of light supplied by a lamp is to

Answer 1

Answer #1

In concave mirror the parallel beam of light is concentrated at focal length and

Radius of curvature = 2× focal length

C = 2 × 2.5 = 5 cm

Answer 2
