`S_(1) and S_(2)` are two coherent sources. The intensity of both sources are same. If the intensity at the point of maxima is `4Wm^(-2)`, the intensity of each source is

Two coherent sources of intensity ratio 9 : 4 produce interference. The intensity ratio of maxima and minima of the interference pattern is

Two coherent sources of intensity ratio 9:4 produce interference.The intensity ratio of maxima and minima of the interference pattern is

Two coherent sources have intensity in the ratio of (100)/(1) . Ratio of (intensity) max/(intensity) min is

Two coherent sources have intensities in the ratio 25: 16. Find the ratio of intensities of maxima to minima after the superposition of waves from the two source.

Two coherent sources have intensities in the ratio 25 : 16 . Find the ratio of intensities of maxima to minima after interference occurs.

S_(1) and S_(2) are two coherent sources of sound of frequency 110Hz each they have no initial phase difference. The intensity at a point P due to S_(1) is I_0 and due to S_2 is 4I_0 . If the velocity of sound is 330m//s then the resultant intensity at P is

Two coherent sources of intensity ratio 81:64 interfere. Deduce the ratio of intensities beween the maxima and minimain the interference pattern.

Interference is produced with two coherent sources of same intensity. If one of the sources is covered with a thin film so as to reduce the intensity of light coming out of it, then
