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 ?

For minimum intensity the phase difference between the two waves is

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

Two waves of intensity I and 9I are superimposed in such a way that resultant Intensity is 7I .Find the phase difference between them ?

Two coherent light waves each having intensities I_(0) interfering at a point in space where resulting intensity observed is I_(0)//2 , the phase difference between the two waves at the point of interference can be :
