5. (20 Points) A screen is placed 1.20 m from two very narrow slits. The distance between the two slits is 0.030mm. When the slits are illuminated with coherent light, the second-order bright fringe on the screen (m=2) is measured to be 4.50 cm from the centerline. 5a (5 pts) Determine the wavelength of the light. 5b (5 pts) Determine the distance between bright fringes. 5c (5 pts) Find the angular position of the interference maximum of order 4. 5d (5 pts) If the slits are not very narrow, but instead each slit has width equal to % of the distance between the slits, you must take into account the effects of diffraction on the interference pattern. Calculate the intensity 1 of the light at the angular position obtained in part 5c in terms of the intensity lo measured at 0=0.
