Question
Define the term ‘linearly polarised light’.
When’ does the intensity of transmitted light become maximum, when a polaroid sheet is rotated between two crossed polaroids?
✓

Answer

When the vibrations of the electric field vector $(\overrightarrow{\text{E}})$ are confined to only one direction then light is called linearly polarized light.Intensity of transmitted light is maximum when the Polaroid sheet makes an angle of $45^\circ$ with the pass axis.

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 $3.0 \times 10^{-3} \mathrm{~kg}-\mathrm{m}^2$ and that of the umbrella is $2.0 \times 10^3 \mathrm{~kg}-\mathrm{m}^2$. The boy starts spinning the umbrella about the axis at an angular speed of $2.0 \mathrm{rev} / \mathrm{s}$ with respect to himself. Find the angular velocity imparted to the platform.
