4 In Young s experiment the distance between two slits is 1 mm and the distance between two consecutive bright fringes is 0 03 cm Now on displacing the screen away from the slits by 50 cm the distance between two consecutive dark fringes is doubled Find the wavelength of light used Ans 6000 5 If the difference of time taken by two waves emitted from coherent sources to reach a point is an integral multiple of the period of the wave show that the constructive interference will occur at that point
