Question

A beam of light in air is incident on the surface of a slab offused quartz. Partof the beam is transmitted into the quartz at an angle ofrefraction of 30-degree relative to a normal to the surface, andpart iss reflected. What is the angle of reflection?? (cf. Index of Fused quartz = 1.46) A beam of light in air is incident on the surface of a slab offused quartz.

Explanation / Answer

use Snell's law n1 sin 1 = n2 sin2 sin 1 = (n2 sin2)/n1 1 = sin-1((n2 sin2)/n1) 1 = sin-1((n2 sin2)/n1) the angle of incidence, 1, is equal tothe angle of reflection
