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 45⁰ with the pass axis.
