Consider the refraction of light ray as shown in the figure below. Incident ray is rotating with constant angular velocity 2 rad/sec. What is the angular velocity of refracted ray, when the angle of incidence becomes 30∘? (Given n1n2=√3)
6 rad/s
n1sin θ1=n2 sin θ2 …(i)
(n1cos θ1)ω1=(n2 cos θ2)ω2 …(ii)
Solving (i) and (ii)
ω2=6 rad/s
