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?
[Malayalam] Light waves from two coherent sources having intensities I
Find the ratio of intensities at two points X and Y on a screen in Young’s double-slit experiment where waves from the slits S1, and S2 have path difference of 0 and respectively.
