Question

in the diagram given below AO is ray of light incident on a rectangular glass slab

Answer 1

Explanation:

Answer

(a) The complete path of incident ray in glass block is drawn in figure below.

(b) Angle of incidence (i) and angle of refraction (r) are marked in part (a). Refractive index (μ) of glass is related to the angles as

sinr

sini

=μ

(c) Angle of emergence (e) is marked in part (a). The two angles are related to each other by the relation ∠i=∠e

(d) Incident ray and emergent ray are parallel to each other.

(e) Lateral displacement is indicated in the figure by XY.
