i am impaired when it comes to math..my teacher asked us to do these practice problems but i have no idea how to find the answer to these can someone help me figure it out??
1) a tuning fork has a frequency of 343 Hz. asecond tuning fork is struck and a student notices a beat frequency of 3 Hz. what are two possible values of the second tuning fork??
2) the middle "C" has a frequency of 256 Hz and a wavelength of 1.3 meters. how fast does this sound travel.

1. The beat frequency is the difference of two other frequencies. So if the difference between 343 Hz and the second frequency is 3 Hz, what are the two possible values of the second frequency?
2. The speed of a wave is the wavelength multiplied by the frequency.
