The fringe separation in a biprism is 3.2 xx 10^-4 m when red light of wavelength 6.4 xx 10^-7 m is used, by how much will this change, if blue light of wavelength 4 xx 10^-7 m is used with the same setting.

In a biprism experiment, the distance between the consecutive bright bands is 0.32 mm, when red light of wavelength 6400 Å is used. By how much would the band width change, if blue light of wavelenth 4800 Å is used, with the same setting?

The distance between two consecutive dark bands in a Young's experiment is 0.32 mm when red light of wavelenght 6400Å is used. By how much will this change if yellow light of wavelength 5900Å is uded with the same setting.
