Why are coherent sources required to create interference of light

Posted by Achieve Goal 6 years, 1 month ago

CBSE > Class 12 > Physics

1 answers

Adi Kumar 6 years, 1 month ago

Coherent sources have almost the same wavelength. Coherent sources are necessary to ensure that the positions of maxima and minima do not change with time. Thereby, producing a sustained interference pattern. ... Wavelength is going to remain the same for incident and reflected light.
