Question

Two guitars are playing together producing a beat frequency. The first guitar is playing at a frequency of 867 Hz and the beat is produced every 0.04 seconds. What are some possible frequencies the other guitar could be playing to make this beat?

Answer 1

The possible frequency of guitar are 842 HZ and 892 HZ.

Step-by-step explanation:

given the beat frequency =
`(1)/(0.04)` = 25 HZ

we know that beat frequency = difference of frequencies of two instruments

therfore 25 = x-867 or 25 = 867-x

therefore x = 842 or 892
