Embibe Experts Solutions for Exercise 1: Exercise

If the intensity ratio of two coherent sources used in Young's double slit experiment is $49:1$, then the ratio between the maximum and minimum intensities in the interference pattern is

What is meant by Constructive interference?

Draw the variation of intensity with position, in the interference pattern of Young's double slit experiment ?

In Young's double slit experiment, a light containing two wavelengths $500 \mathrm{nm}$ and $700\mathrm{mn}$ are used. Find the minimum distance where maxima of two wavelengths coincide. Given $\frac{\mathrm{D}}{\mathrm{d}}={10}^3$, where D is the distance between the slits and the screen and d is the distance between the slits.

Derive the expression for the intensity at a point where interference of light occurs. Arrive at the conditions for maximum and zero intensity.

Define coherent sources of light.

Two coherent sources of light of intensity ratio n produce interference pattern. Prove that in that pattern $\frac{{\mathrm{I}}_{\max }-{\mathrm{I}}_{\min }}{{\mathrm{I}}_{\max }+{\mathrm{I}}_{\min }}=\frac{2\sqrt{\mathrm{n}}}{1+\mathrm{n}}$
