See the step by step solution

Step by Step Solution

Step: 1 Diffraction grating:

A optical device is an device that splits multicoloured light into its beam is split (disperses colors). The polychromatic light received on the grating is scattered, ends up in each wavelength becoming reflected at a replacement angle from the grating.

Step: 2 Finding position:

The fringe position by

The angle by

Step: 3 Finding the width:

Two variable wavelength by

where,

The rainbow width by
