A student holds a laser that emits light of wavelength 633 nm.The beam passes through a pair of slits separated by 0.300 mm, in aglass plate attached to the front of the laser. The beam then fallsperpendicularly on a screen, creating an interference pattern onit. The student begins to walk directly toward the screen at 3.00m/s. The central maximum on the screen is stationary. Find thespeed of the first-order maxima on the screen.
