Final answer:
The part of a radio that receives electromagnetic waves is the antenna. It converts received waves into electrical signals, which are then processed and amplified by the radio's tuner to be converted into audio by the speakers.
Step-by-step explanation:
The part of your radio that receives the electromagnetic waves sent out from a radio station is the antenna. Electromagnetic waves carry energy and when these waves reach your radio, the antenna induces oscillating currents, which represent the original sound waves. The radio's tuner circuit, which includes a tuning dial, allows you to select the specific frequency of the desired broadcast. The tuner responds to the frequency of the chosen station and filters out others. Once the signal is received, electrical components within the radio amplify the signal, which is then converted into an audio format by the speakers for you to hear.
