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

It is found that what waves of same intensity from two coherent sources superpose at a certain point, then the resultant intensity is equal to the intensity of one wave only. This means that the phase difference between the two waves at that point is

Two waves of intensities 1 and 41 superpose, then the maximum and minimum intensities are ...... and ...... respectively.

Two coherent light beams of intensities I and 4I superpose in a region. Find the maximum and minimum possible intensities due to superposition in this region.

Two coherent monochromatic light beams of intensities I and 4I are superposed. What is the maximum and minimum possible intensities in the resulting beam ?

Light waves from two coherent sources having intensities I and 2 I cross each other at a point with a phase diff. of 60^(@) . What is the resultant intensity at the point ? If the sources were incoherent, what would be the resultant intensity ?
