In an interference experiment monochromatic light is replaced by white light, we will see:
If the Young’s apparatus is immersed in water, the effect on fringe width will
Two coherent sources produce a dark fringe when phase difference between the interfering waves is(n integer)
Dark fringes will be produced when there are destructive interference. The condition for that is the two waves should have a phase difference of an odd integral multiple of π.
In Young’s double slit experiment, the distance between the two slits is halved and the distance of the screen from the slit is doubled. The fringe width will be
Young’s double slit experiment is carried out using two bulbs instead of using two slits and one source. Then
In the Young’s double slit experiment, the distance of p th dark fringe from the central maximum is:
In Young’s double slit experiment, one slit is covered. The observed effect will be
When viewed in white light, a soap bubble shows colours because of
Two coherent sources of intensity ratio 100:1 interfere. The ratio of interference at the maxima and minima
We know that for two coherent sources, the intensity of their maxima is (Imax + Imin)2 and that of its minima is (Imax + Imin)2 . Thus we get the intensity of maxima = 121k and that of minima = 9k, for some constant k as (Imax = 100k and Imin = k.
Thus we get the ratio as 121:81.
Which of the following in conserved when light waves interfere?
