Embibe Experts Solutions for Chapter: Wave Optics, Exercise 1: Nagaland Board-2018

Use Huygen’s principle to verify the laws of refraction.

Define polarizing angle. Derive the relation connecting polarizing angle and the refractive index of a medium.

Explain Young’s double slit experiment to produce interference pattern due to monochromatic source of light. Deduce an expression for fringe-width.

Explain diffraction of light due to a single slit and illustrate formation of a pattern of fringes obtained on the screen and plot a graph showing variation of intensity with angle $\mathrm{\theta }$ in single slit diffraction.

State Huygen’s principle of diffraction of light.

In a Young’s double slit interference experiment, the ratio of intensity at the maxima and minima in the interference pattern is $\frac{25}{9}$ . What will be the ratio of amplitudes of light emitted by the two slits?

Derive the expression for the fringe width of the bright and dark fringes in Young’s double slit experiment for interference of light.
