Question
Does the polarising angle for any transparent medium depend on the wavelength of light?
✓

Answer

Yes, Reason: Angle of polarisation $\text{i}_\text{B}=\tan^{-1}(\text{n})$ and since refractive index varies as inverse of square of wavelength so angle of polarisation decreases with increase of wavelength.

A boy is standing on a platform which is free to rotate about its axis. The boy holds an open umbrella in his hand. The axis of the umbrella coincides with that of the platform. The moment of inertia of ''the platform plus the boy system'' is $3.0 \times 10^{-3}kg-m^2$ and that of the umbrella is $2.0 \times 10^3\ kg-m^2$. The boy starts spinning the umbrella about the axis at an angular speed of $2.0\ce{rev/s}$ with respect to himself. Find the angular velocity imparted to the platform.
