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 ?
Text Solution
Verified by Experts
If ligth is monochromatic, a dark fringe will be formed at the point. However, if ligth is white, the fringe seen will be coloured. However, the yellow colour and its neighbouring colours shall be absent.

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
Two coherent source of light can be obtained by
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 Young's double slit experiment, the intensity on the screen at a point where path difference is lambda is K. What will be the intensity at the point where path difference is lambda//4 ?
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 ?
Two light sources are said to be coherent if they are obtained from
Two light sources are coherent when
In Young’s double slit experiment, light from two identical sources are superimposing on a screen. The path difference between the two lights reaching at a point on the screen is frac{7 lambda}{4} . The ratio of intensity of fringe at this point with respect to the maximum intensity of the fringe is :
