In an interference experiment, third bright fringe is obtained at a point on the screen with a light of 700 nm . What should be the wavelength of the light source in order to obtain 5th bright fringe at the same point

In the interference pattern obtained in a biprism experiment, 5th order bright fringe is obtained at a point on the screen, when monochromatic light of wavelength 6000 Å is used. What is the order of the bright fringe produced at the samme point, if the light of wavelength 5000 Å is used?

In a biprism experiment, using monochromatic lightof wavelength 6000 Å, 8th bright band is obtained at a point on the screen. What is the wavelength of the another source, which produces the 12th bright band at the samme point?

A light of wavelength 4000 overset@A forms third bright fringe at some point on the screen in Young’s double slit experiment. Find the wavelength of light which will form second bright fringe at the same point.

In Young's double slit experiment, red light of wavelength of 6000Å is used and the n^(th) bright fringe is obtained at a ponit P on the screen. Keeping the same setting, the source of light is replaced by green light of wavelength 5000Å and now (n+1)^(th) bright fringe is obtained at the point P on the screen. The value of n is
