Question

An initially parallel cylindrical beam travels in a medium of refractive index $μ (I) = μ_{0} + μ_{2} I$ , where $μ_{0}$ and $μ_{2}$ are positive constants and $I$ is the intensity of the light beam. The intensity of the beam is decreasing with increasing radius. As the beam enters the medium, it will

Options:

Answer:

B

Solution:

As intensity is maximum at axis, $∴ μ$ will be maximum and speed will be minimum on the axis of the beam. $∴$ beam will converge.
