Question

Is the beat frequency produced when a 245 Hz tone and a 240 Hz tone are played together greater than, less than, or equal to the beat frequency produced when a 140-Hz tone and a 145-Hz tone are played together? greater than less than equal to Choose the best explanation from among the following: The beat frequency is determined by the difference in frequencies and is independent of their actual values. The percentage change in frequency for 240 and 245 Hz is less than for 140 and 145 Hz, resulting in a lower beat frequency. The higher frequencies will produce a higher beat frequency.

Explanation / Answer

part A

beat frequency between 245Hz and 240 Hz is = 245-240=5 HZ

beat frequency between 145HZ and 140 HZ is= 145-140 =5 HZ

so in both cases beat frequency will be same.

part B

ANSWER IS OPTION A the beat frequency is determined by the difference in frequencies and is independent of thier actual values.
