Question: Coherent microwave light with a frequency f = 2.0 x 10^10 Hz is incident on a d = 5.0 cm double slit barrier, producing an interference pattern of a number of maxima and minima. A detector is free to swing around the full 180 degrees in order to find the presence of interferenece maxima and minima. How many different minima will this detector detect, as it is allowed to swing around the full 180 degrees? (Include minima on both sides of the centerline in your count).
