A microwave is equipped with two sources of microwave light that emit at a frequency of f = 18.8 GHz. The two sources are housed in an air-filled chamber as shown below. The spacing between the sources is d = 5.00 cm. The distance from the left source to the left wall is x, = 17.5 cm. The dimensions of the chamber are height y = 50.0 cm and width x = 84.0 cm. (a) Using both the parallel-ray approximation and the small-angle approximation, what is the location of the right-side 1st-order maxima relative to the upper-right corner of the chamber? (b) What is the percent error between the calculated location above and one where the small-angle approximation is not used? (c) What is the highest order maximum that is visible along the upper side of the chamber? Do not use the small angle approximation.
