Light from two coherent sources of the same amplitude 
and wavelength 
illuminates the screen. The intensity, of the central maxima is 
. If the sources were incoherent, the intensity at the same point will be:
Text Solution
Verified by ExpertsD
The rays of light from two coherent sources superimpose each other on the screen forming alternate maxima and minima. For two sources of equal intensities the intensity of the maxima is four times the individual intensities. If two non-coherent sources superimpose, there will be no maxima and minima, instead the intensity will be 
throughout.
