Question

The frequencies of two tuning forks are measured to be 339 Hz and 349 Hz respectively. If the two forks make a sound beat, what is the beat frequency (in unit of Hz)? In the lab you will be using one of two combinations of two tuning forks to produce a beat wave. What combinations of forks will be available for you to use? 125Hz and 128Hz 125Hz and 250Hz 125Hz and 250Hz 128Hz and 256Hz 125Hz and 128Hz 250Hz and 256Hz 125Hz and 128Hz 128Hz and 256Hz When striking the tuning forks they will produce two distinct sounds, a high-pitched ringing and a low-pitched humming. In order to get a smooth curve you must start recording after which sound fades away? Ringing Humming We should record both.
