You know the diffraction pattern from single slit looks like but which one of these is the diffraction pattern from a circular aperture?

Which of the following diagrams represent the diffraction patterns of two points that are just resolved?

To observe interference in thin films with a light of

wavelength λ, the thickness of the film

Interference pattern is observed in wedge-shaped film for monochromatic

light. Now monochromatic light is replaced by white light. What will be the effect

on interference pattern?

If instead of monochromatic light white light is used for interference of light, what would be the change in the observation?

The bright and dark

bands you see in a photograph of a double slit interference pattern represent

Each pattern shown

below would appear on a screen when monochromatic light first passes through a

narrow slit of width

Two light sources are said to be coherent if they

If the distance between two slits is increased in Young's Experiment the fringes width 

For all transparent material substances, the index of refraction
