The problem then goes on and asks me how to find the speed which I know how to do I just don't know how to find the period...

Please show me how to do and the formulas to use thanks for the help

**drwls**, Sunday, May 17, 2009 at 11:54amYou cannot get the period from the wavelength and amplitude alone. You need to know the speed.

Knowing the amplitude does not help. Speed is independent of amplitude.
