,.Showthatmaximumintensityininterferencepatterm is four times theintensity due to each slit if amplitude of light emerging from slits issame |
|
Answer» Intensity is directly proportional to the square of amplitude 'a'.As both slits have same intensity both have the same amplitude. Constructive interference is due to mixing of waves in phase and hence maxima.As in phase then amplitudes have to be added. So a+a = 2aSquare of this gives the intensity of maximum. So 4 a2Hence 4 times the intensity of light being used |
