s double slit experiment usingmonochromatic light, the fringe pattern shifts bycertain distance on the screen when mica sheetof refractive index 1.6 and thickness 1microns is introduced in the path of one of theinterfering waves. The mica sheet is thenremoved and the distance between the slits andscreen is doubled. It is found that the distancebetween successive maxima now is same as theobserved fringe shift upon the introduction ofthe mica sheet. Calculate the wavelength of themonochromatic light used in the experiment. |
