5. Two narrow parallel slits seperated by .25mm areilluminated by green light ( = 546.1nm). The interferencepattern is observed on a screen 1.2m away from the plane of theslits. Calculate the distance a. from the central maximum to the first bright region oneither side of the central maximum and b. between the first and second dark bands 5.

Explanation / Answer

separation of the slits d = 0.25 mm = 25 * 10 ^ -5m wavelength = 546.1 nm = 546.1 * 10 ^ -9 m distance of the screen from the slits d = 1.2 m (a). distance from the central maximum to the first brightregion on either side of the central maximum = 3 where = fringe width = D / d substitue values we get answer (b). distance between the first and second dark bands =
