Question

You hear a tone and recognized it to me 512 Hz and you know that the speed of sound

is 340 m/s at the surface of the earth. What is the wavelength of the sound?
Answer with three significant figures.

Answer 1

Step-by-step explanation:

The frequency equation is

`f=(v)/(\lambda)` where f is frequency measured in Hz, v is velocity of sound measured in m/s and
`\lambda` is wavelength measured in meters. Filling in our given info:

`512=(340)/(\lambda)` and

`\lambda=(340)/(512)` so

`\lambda=.664 m` (That is the incorrect number of sig dig's by the way. It should only be 2 since the number 340 only has 2 sig dig's)
