Consider a road that runs parallel to the line connecting a pair of radio towers that transmit the same station (assume that their transmissions are synchronized), which has an AM frequency of 1000 kilohertz. If the road is 5 kilometers from the towers and the towers are separated by 400 meters, find the angle to the first point of minimum signal (m=0). Hint: A frequency of 1000 kilohertz corresponds to a wavelength of 300 meters for radio waves. Express your answer in radians, to two significant figures. Because it's constructive interference i think we use dsin(theta) = m x lambda So that would be: 400 x sin(theta) = 0 x 300 Is this correct? And if so how would you go about working it out?
