A sound wave has a frequency of 9780 Hz and travels

Question

A sound wave has a frequency of 9780 Hz and travels along a steel rod. If the distance between compressions, or regions of high pressure, is 0.595 m, what is the speed of the wave?

___ m/s

i have more similar problems like this..so if anyone has some time on thier hands and is willing to explain to me how to solve sound wave problems that would be AMAZING!!!!! (im taking a online summer class and the book does not teach the lessons very well) send me you email

Answer 1

I think rijim2008 has the correct approach using the wave equation,

v = f x L , but I believe that the distance from compression to compression IS the wavelength. This is the distance between two points that are in phase--the wavelength.

Answer 2

If the distance between compressions, or regions of high pressure, is 0.595 m, then the wavelength is 2 x 0.595 m = 1.19 m

v = f x L = 9780 Hz x 1.19 m = 11 638.2 m / s
