Two pianos each sound the same note simultaneously, but they are both out of tune. On a day when the speed of sound is 348 m/s, piano A produces a wavelength of 0.765 m, while piano B produces a wavelength of 0.772 m. How much time separates successive beats?(adsbygoogle = window.adsbygoogle || []).push({});

So I know:

v=348 m/s

wavelength of A=0.765 m

wavelength of B=0.772 m

f=v/wavelength

so I was able to find the frequency of A=454.9 and frequency of B=450.7

I'm just not really sure what I should be doing... seems like it should be just a one or two step problem.. :/

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
