Question

A beam of
parallel rays in insident on a transparent block at an angle of incidence 45 .If the ratio of widths of incident beam root 2:root 3 and refractive index of block

Answer 1

Using μ1​sini=μ2​sin r

1×sin60∘=3

​ sin r

sin r=21​

AB=cosi1.732mm​

Now,

BB1=AB cos r

=cosi1.732​×cos r

=21​1.732​ ×23

​​=3 mm

A ray of light falls on three glass slabs of the same material at the same angle of incidence. In which case, is the lateral displacement of the emergent ray of light

(a) maximum

(b) minimum

1 Verified Answer

A light ray passes from air to denser medium of certain thickness and emerges on the other side. If the emergent ray is parallel to the incident ray, the distance traveled by the ray of light in the denser medium is 6 cm, and the angle of incidence and refraction are 600 and 300 respectively, find the lateral displacement of the light ray.
