Question

Q. A ray is incident on a surface of a parallel sided
glass slab and gets refracted as shown in figure,
may and emergent ray from the
given diagram
b) Name the phenomenon involved here.
c) If the angle of incidence (1) is 60°, then what is the
value of angle of emergence (e)? Give reason.
d) Define
Lateral
displacement​

Answer 1

b ) The phenomenon is Refraction of Light.

.

d) The perpendicular distance between the original path of incident Ray and the emergent Ray coming out of the glass slab is called lateral displacement of the emergent Ray of light
