A light source of unknown wavelength is incident normally on a glass plate which is placed over another glass plate at an angle 0.8deg. There is an air film of varying thickness created between them. If the two consecutive bright fringes are obtained at 3mm distance what is the wavelength of the light. The interference pattern considered above is the interference of reflected rays.The length of the glass plate is 10cm.
