In a polarizer-analyzer combination, 90.0% of the light intensity falling on the analyzer is absorbed. Determine the angle between the transmission axes of the polarizer and analyzer.
Two friends are playing with hand-held radio transceivers which have dipole antennas. If the antenna of the transmitting radio is vertical, and the antenna of the receiving radio is at an angle ? to the vertical, what is the received power as a percentage of the maximum possible received power at the receiving antenna in the following cases?
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 θ 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.
