Question

A "showy" custom-built car has two brass horns that are supposed to produce the same frequency but actually emit 263.8 and 264.5 Hz. What beat frequency is produced?

a) (0.7 Hz)
b) (0.9 Hz)
c) (1.1 Hz)
d) (1.3 Hz)

Answer 1

The beat frequency produced by the two horns is 0.7 Hz.

Step-by-step explanation:

The beat frequency produced by two brass horns emitting frequencies of 263.8 Hz and 264.5 Hz can be calculated by subtracting the lower frequency from the higher frequency. In this case, the beat frequency is 264.5 Hz - 263.8 Hz = 0.7 Hz. Therefore, option a) (0.7 Hz) is the correct answer.
