Question
In an experimental arrangement of a Fresnel's biprism, monochromatic light of wavelength 2. is used to produce interference fringe pattern. On introducing a thin, transparent glass sheet of refractive index 1.50 and thickness of 7 microns in the path of one of the interfering beams, the central fringe of the pattern is shifted to the position of 6th bright fringe. Then, the wavelength of the monochromatic light used is nearly:
