The ratio of light intensity at the maxima and minima in an interference pattern is 4:1. Find the ratio of intensity of light of two slits.

In Young's double slit Interference experiment the ratio fo the intensities of the maxima to minima in the interference pattern is 9:1. the ratio of the amplitudes of the superposing waves is

Two identical coherent waves, each of intensity I are producing an interference pattern. find the value of the resultant intensity at a point of constructive interference.

The intensities of the two interfering beams are in the ratio 64:49. The ratio of the intensities of the minima to maxima is
