Question
Chapter 31, Problem 15A
To determine
The difference between the laser light and the ordinary lamp light.
Expert Solution & Answer
Explanation of Solution
Introduction:
Two wave sources are said to be perfectly coherent when they have same waveform, frequency and also have a constant phase difference.
Two wave source are said to be incoherent when they do not have identical frequency and wavelength.
Light from laser source is coherent in nature that is the light has same phase, frequency and waveform while the light from the ordinary table lamp is incoherent in nature that is the light do not have same frequency and phase.
