Fresnel Diffraction
Fresnel Diffraction: Overview
This topic covers concepts, such as Fresnel Diffraction, Properties of Fresnel Diffraction, Fresnel Distance between Source and Screen, Fresnel Shape of Incident or Diffracted Wavefront, Fresnel Distance, Condition For Validity of Ray Optics, etc.

Which one of the following statement is true for both the interference and diffraction?
Light of wavelength is incident on an aperture of size . The distance upto which light can travel such that its spread is less than the size of the aperture is
For what distance ray optics is a good approximation when the aperture is and the wavelength of light is ?
Diffraction pattern of a single slit consists of a central bright band which is
Fresnel diffraction is produced due to light rays falling on a small obstacle. The intensity of light at a point on a screen beyond an obstacle depends on
In a Frensel biprism experiment, the two positions of lens give separation between the slits as 16 cm and 9 cm respectively. What is the actual distance of separation?
A screen is at a distance of 1 m away from the aperture. If light of wavelength 500 nm falls on an aperture, then calculate area of first HPZ and radius of third HPZ
