Light from two coherent sources is reaching a point where path difference for yellow light is `3 lambda//2`. What will be the colour of the fringe at that point ?

Assertion (A) : Light from two coherent sources is reaching the screen. If the path difference at a point on the screen for yellow light is 3 lambda//2 , then the fringe at the point will be coloured. Reason (R ) : Two coherent sources always have constant phase relationship

A : Light from two coherent sources is reaching the screen. If the path difference at a point on the screen for yellow light is 3lambda"/"2 , then the fringe at the point will be coloured. R : Two coherent sources always have same phase relationship at any point on the screen.

Light from two coherent sources is reaching the screen. If the path difference at a point on the screen for the yellow light be (3lambda)/2 , then what will be the colour of the fringe at that point?

Light waves from two coherent source arrive at two points on a screen with path difference 0 and lambda//2 . Find the ratio of intensities at the points.

In a Young's double slit set up using monochromatic light of wavelength lambda the intensity of light at a point, where path difference is 2lambda is found to be I_(0) What will be the intensity at a point when path different is lambda//3 ?
