Two sources of intensities I and 4I and waves, which interfere to produce a resultant intensity `I_0` at a point of phase difference `pi//2. I_(0)` is equal.

Two sources of light of intensities I and 4I emit light waves which interfere at a point. Intensity will be ..... At points where the phase difference, is

Two coherent light beams of intensities I and 4I produce interference pattern. The intensity at a point where the phase difference is zero, will b:

Two coherent light beams of intensities I and 4I produce interference pattern. The intensity at a point where the phase difference is zero, will b:

Two coherent waves of intensities I and 4I interfere at a point. If the resultant intensity is 3I, then the phase difference between te two waves at the point is

Waves from two sources of intensities I and 3I are used in an interference experiment. Calculate the intensity at point where the waves superimpose with a phase difference of (i) pi//2 and (ii) pi .

Two waves having intensity I and 9I produce interference . If the resultant intensity at a point is 7 I , what is the phase difference between the two waves ?
