Q2.a)Find the condition of maxima and minima in case of interference of light by a wedge shaped film.

     b)In Fresnel's biprism experiment,on inserting a thin transparent glass plate(refractive index 1.5) in the path of one of the interfering beams of light(wavelength 6000 A),it is found that central bright fringe shifts in to the position already occupied by 5th bright fringe.Calculate the thickness of the glass plate.
