Ratio of intensities between a point A and that of central fringe is 0.853. If we consider slits are of equal width then path difference between two waves at point A will be :

If the path difference between two waves at a point is 29 lamda , then the point will be

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

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

In double slit experiment, the point on the screen where 3^(rd) order dark fringe from central position is obtained, phase difference between two waves will be .....

Find the ratio of intensities at two points on a screen in young’s double slit experiment when waves from the two slits have path difference of 0 and λ/4.

The slits in a Young's double slit experiment have equal width and the source is placed symmetrically with respect to the slits. The Intensity at the central fringe is I_0 . If one of the slits is closed, the intensity at this point will be

The slits in a Young's double slit experiment have equal width and the source is placed symmetrically with respect to the slits. The Intensity at the central fringe is I_0 . If one of the slits is closed, the intensity at this point will be
