Question

What is difraction of light? State the rules of defraction of light.

Answer 1

$\huge \sf \green{Hello \: mate}$

When light waves find obstacles on their path, the bend around the corners of the obstacles.

If they travel in straight lines, then one expects some shadow behind obstacles. But the bending of light wave and its falling in the expected shadow region is diffraction.

Due to this effect, there is an interference between light waves in that region and one may see regions of higher and lower intensities alternately - diffraction pattern.

For example :

The closely spaced tracks on a CD or DVD act as a diffraction grating to form the familiar rainbow pattern seen when looking at a disc.
