Maintaining strong AM radio reception when driving under overpasses or through tunnels is often difficult. FM radio
Question:
(a) Using the frequency range for AM radio, 550 kHz to 1650 kHz, and FM radio, 88 MHz to 108 MHz, find the range of wavelengths for both AM and FM bands.
(b) In terms of wave diffraction, explain why AM radio waves have a more difficult time passing under overpasses and through tunnels.
