Write definitions of plane of vibration and plane of polarisation.

Explain the working process to obtain plane polarised light by Nicol Prism.

Draw necessary diagram.

Write definitions:

Diffraction of light.

Write formula related to Malus law.

When light is incident at ${60}^{\mathrm{o}}$ on a transparent sheet, the reflected light is completely polarised. Find the refractive index of the substance and refraction angle.

Draw a ray diagram to produce interference fringe pattern in Young's double slit experiment. Derive an expression for fringe width of bright fringes.

In Young's double slit experiment, fringe width is $2 \mathrm{mm}$. Find distance of second dark fringe from central fringe.

Write any two differences between and interference of light.

What is wave front? Explain laws of refraction of light on the basis of Huygens wave theory. Draw necessary ray diagram.
