The waves have frequency 3.0 MHz and the distance between antennas is d = 0.30 km.
(a) What is the difference in the path lengths traveled by the waves that arrive at the detector at θ = 0°?
(b) What is the difference in the path lengths traveled by the waves that arrive at the detector at θ = 90°?
(c) At how many angles (0 ‰¤ θ (d) Find the angles (θ) of the maxima in the first quadrant (0 ‰¤ θ ‰¤ 90°).
(e) Which (if any) of your answers to parts (a) to (d) would change if the detector were instead only 1 km from the towers? Explain. (Don't calculate new values for the answers.)
