Embibe Experts Solutions for Chapter: Wave Optics, Exercise 1: Exercise

Assume that the pupil of the human eye has a diameter of $4.00\mathrm{mm}$ and receives the light of wavelengths $5.0\times {10}^{-7}\mathrm{m}$.

b. Estimate the least distance between features on the Moon (a distance of $3.8\times {10}^8 \mathrm{m}$away) that can be resolved by the human eye.

What is meant by fresnel distance$?$

In Young's double slit experiment, deduce the condition for  constructive 

Is the bright fringe in interference-pattern obtained by violating the Principle of conservation of energy ?

Can two independent monochromatic sources of light be coherent ? Explain.

What are coherent sources of light? Why are coherent sources required to obtain sustained interference patterns?

When light waves from two coherent sources interfere, they produce darkness at some points. What becomes of the energy ?

What type of wave is produced by: a point source of light.
