2) A laser beam is incident on two slits with a separation of 0.200 mm, and a screen is placed 5.00 m from the slits. An interference pattern appears on the screen. If the distance from the center maximum to the first maximum to the side is 1.58cm, what is the wavelength of the laser light? y tan 0 = D For distant screen assumption Assumption of infinite source distance gives plane wave at slit so that all amplitude elements are in phase. tan 0 - sin0 ~ 0 ~ 2 D D For D >> a this approaches a right angle and O' = 0 Condition for maximum d sin 0 = mr mAD У» d a = slit width
