Types of Diffraction

The spreading of light around the edge of an aperture or obstacle is called the diffraction. This notes provides ua an information on types of diffraction.

Diffraction Grating and Resolving Power

A diffraction grating consists of a large number of equally spaced, parallel slits of the same width ruled on glass or polished metal by a diamond point. This note provides us an information on the diffraction grating and resolving power.
