Interference and resultant intensity

Assertion Two coherent sources transmit waves of equal intensity I_(0) Resultant intensity at a point where path difference is lambda/3 is also I_(0) . Reason In interference resultant intensity at any point is the average intensity of two individual intensities.

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 ?

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.

In a destructive interference of sound the resultant intensity of sound at a point of medium is

Two incoherent sources of intensities l and 4l superpose then the resultant intensity is

Two identical coherent waves each of intensity I_(0) are producing interference pattern. What are the values of resultant intensity at a point of (i) constructive interference (ii) destructive interference ?

Two waves of intensities I and 4I produce interference. Then the intensity at constructive and destructive interference respectively is –

Two beams of light having intensities I and 4I interfere to produce a fringe pattern on a screen. The phase difference between the beams is pi//2 at point A and pi at point B. then the difference between the resultant intensities at A and B is

Two sinusoidal waves of intensity I having same frequency and same amplitude interferes constructively at a point. The resultant intensity at a point will be
