For distinct interference pattern to be observed, necessary condition is that ratio of intensity of light emission by both the sources should be :

For the sustained interference of light, the necessary condition is that the two sources should

For the sustained interference of light, the necessary condition is that the two sources should

For the sustained interference of light, the necessary condition is that the two sources should

For the sustained interference of light, the necessary condition is that the two sources should

For the sustained interfernce of light, the necessary condition is that the two source should :

A : For best contrast between maxima and minima in the interference pattern of Young.s double slit experiment, the intensity of light emerging out of the two slits should be equa. R : The intensity of interference pattern is proportional to square of amplitude.

The ratio of the intensities of the maxima and minima in an interference pattern is 49: 9. What is the ratio of the intensities of the two coherent sources employed in the interference experiment?
