Question

Find the deviation in the path of ray of light incident on a glass slab of refractive index 1.5 at an angle 60 with the surface.​

Answer 1

Answer:

Ray of light enters the glass slab normally.

Angle of incidence, i=0

0

Let the angle of refraction be r.

Using Snell's law:

n

1

sin i=n

2

sin r

1 sin 0

0

=n

2

sin r

sin r=0

0

⇒r=0

0

This means that the ray continues along its original path implying no deviation
