Question

A special base station radio that receives messages and signals on one frequency and then automatically retransmits them on a second frequency?

a) True
b) False

Answer 1

Waves can superimpose if their frequencies are different, creating an interference pattern known as beats.

Step-by-step explanation:

The statement is true. Waves can superimpose if their frequencies are different. When two waves with different frequencies combine, they create an interference pattern known as a beat. The beat frequency is given by the difference between the frequencies of the two waves. This phenomenon is commonly observed in music, where beats are produced when two slightly different frequencies are played together.

For example, if a sound wave with a frequency of 440 Hz (A4) and another sound wave with a frequency of 436 Hz are played simultaneously, beats at a frequency of 4 Hz will be heard. The beats are caused by the constructive and destructive interference of the two waves at different points in space and time.
