4 In a Young s double slit experiment the fringes are displaced by a distance x when a glass plate of refractive index 1 5 is introduced in the path of one of the beams When this plate is replaced by another plate of same thickness the shift of fringes is 3 2 x The refractive index of second plate is a 1 75 c 1 25 b 1 40 d 1 67
