# Beat frequency heard from two tuning forks

Andrew Tom
Homework Statement:
Beat frequency
Relevant Equations:
Beat frequency

Is my solution correct?

I used v=lambda*f, i.e. f=v/lambda to get the frequency for each wave. Then I calculated the average of the frequencies to get 258Hz and found the beat frequency by doing f1-f2 to get 4Hz. I then said that this means the observer will hear a tone of frequency 258Hz which rises and falls in intensity 4 times per second.

Hi,

No Joy with ##\LaTeX## ?

PF isn't for stamp-approving homework answers.
On the other hand, I find no obvious errors in your calculation.
Are you allowed to use 332 m/s as speed of sound ?

Thank you I will use LaTeX next time.

It is given as 330 in the formula booklet so I don't think so.

Would it be ok to just post the question rather than asking for confirmation of my answer? Or is there some other way it should be done?
