Coherent, monochromatic light of unknown wavelength enters a double slit apparatus with unknown slit spacing. (You can assume that the slit width is very small, so that you can neglect diffraction effects.) On a distant, infinitely large screen, we observe that the 5th order maximum (not counting the central maximum) occurs at an angle of 49 above the optic axis. (a) What is the total number of bright fringes on the screen? (b) What is the angular spread of the 5th order bright fringe? (In other words, what is the angle difference between the neighboring dark fringes above and below the 5th order maximum?)
