Question

How will you produce coherent sources of light?

Answer 1

We can produce coherent sources of light in the following ways:-

Firstly, we need to understand that coherent sources of light are the sources that emit light waves of equal frequency, wavelength, and constant phase difference.

In order to produce a coherent source of light,

• We can divide the wavefront into equal parts which then reunite just as in Young's Double Slit Experiment.
• The other method is to divide the amplitude by reflection or diffraction.
