In interference pattern, using two coherent sources of light, the fringe width is …… .

Two sources of light P and Q have wavelengths 6000 Å and 5500 Å respectively. In a biprism experiment, first the source P is used, and then it is replaced by the source Q. it is found that the position of the n^(th) bright band corresponding to P is occupied by (n+1)^(th) bright band of Q. what is the value of n?

Discuss the pattern of interference fringes obtained on the screen away from the two point sources.

In Young.s double slit experiment, slits are separated by 2 mm and the screen is placed at a distance of 1.2 m from the slits. Light consisting of two wavelengths 6500Å and 5200Å are used to obtain interference fringes. Then the separation between the fourth bright fringes of two different patterns produced by the two wavelengths is
