The central fringe of the interference pattern produced by the light of wavelength 6000 Å is found to shift to the position of 4th dark fringe after a glass sheet of refractive index 1.5 is introduced. The thickness of glass sheet would be

A central fringe of interference pattern produced by light of wavelength 6000 Å is shifted to the position of 5th bright fringe by introducing thin film of mu = 1.5 . Calculate thickness of the film.

In YDSE, the central bright fringe produced by light of wavelength 5600 Å shifts to the position of 5th bright fringe when a thin transparent film of refractive index 1.28 is introduced in the path of light from one of the two slits. Find the thickness of the film.

To make the central fringe at the center O , mica sheet of refractive index 1.5 is introduced Choose the corect statement(S).

The central fringe shifts to the position of fifth bright fringe, if a thin film of refractive index 1.5 is introduced in the path of light of wavelength 5000 Å . The thickness of the glass plate is

Light of wavelength 6000 Å is reflected at nearly normal incidence from a soap films of refractive index 1.4 The least thickness of the fringe then will appear black is

Fringes are produced with monochromatic light of wavelength 5500 Å. A thin glass plate of R.I. 1.5 is then placed normally in one of the paths of interfering beams and the central bright fringe is found to be shifted to the position, previously occupied by the third bright band from the centre. the thickness of the glass plate is

Green light of wavelength 5460Å is incident on an air glass interface. If the refractive index of glass is 1.5, the wavelength of light in glass would be (C=3 xx 10^(8) ms^(-1)) n

Fringes are produced with monochromatic light of wave-length 5.45xx10^(-5) cm. A thin glass plate of refractive index 1.5 is then placed normally in the path of one of the interference beams and the central bright band of the fringe system is found to move into the position previously occupied by the third bright band from the system. Find the thickness of the glass plate.
