When the plastic thin film of refractive index `1.45`is placed in the path of one of the interfering waves then the central fringe is displaced through width of five fringes.The thickness of the film will be ,if the wavelength of light is`5890Å`

In Fresnel's biprism experiment a mica sheet of refractive index 1.5 and thickness 6xx10^(-6)m is palced in the path of one of interfering beams as a result of which the central fringe gets shifted through five fringe widths. Then calculate the wavelength of light.

When a thin transparent plate of thickness t and refractive index mu is placed in the path of one the two interfering waves of light, then the path difference changes by

On introducing a thin film in the path of one of the two interfering beam, the central fringe will shift by one fringe width if mu=1.5 , the thickness of the film is (wavelength of monochromatic light is lamda )

On introducing a thin film in the path of one of the two interfering beam, the central fringe will shift by one fringe width. If mu=1.5, the thickness of the film is (wavelength of monochromatic light is lambda )

When a mica sheet of thickness 7 microns and mu=1.6 is placed in the path of one of interfering beams in the biprism expriment then the central fringe gets at the position of seventh bright fringe. What is the wavelength of light used?
