Radio Waves and Applications

Question 7 • Physics B Spring 2026 Mr Edge

Which statement correctly differentiates between transmitters and receivers?

Answer
A
Transmitters have antennas, and receivers do not have antennas.
B
Transmitters send radio waves, and receivers capture radio waves.
C
Transmitters have demodulators, and receivers have modulators.
D
Transmitters do not have amplifiers, and receivers have amplifiers.

Explanation

A transmitter sends information as radio waves, while a receiver captures those radio waves and recovers the information. Both types of equipment can use antennas, so A is incorrect. Modulators are associated with transmitters and demodulators with receivers, making C reversed.
