Light waves from two coherent sources having intensities I and 2I cross each other at a point with a phase difference of 60°. What is the resultant intensity at the point?

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 ?

Two monochromatic light waves of amplitude 3A and 2A interfering at a point have a phase difference of 60^(@) . The intensity at that point will be proportional to:
