Question

A car has two horns, one emitting a frequency of 199 Hz and the other emitting a frequency of 203 Hz. What beat frequency do they produce?

a) 4 Hz
b) 2 Hz
c) 402 Hz
d) 200 Hz

Answer 1

The beat frequency produced by the two horns is 4 Hz.

Step-by-step explanation:

To find the beat frequency produced by the two horns, we need to subtract the frequencies of the horns. In this case, the beat frequency is given by:

203 Hz - 199 Hz = 4 Hz

Therefore, the correct answer is option a) 4 Hz.
