Homework Statement


Dogs are able to hear mucher hgher frequencies than humans are capable f detecting. For this reason, dog whistles that are inaudible to the human ear, can be easily heard by a dog. If a dog whistle has a frequency of 30,0000 Hz, what is the wavelength of sound emitted.

Homework Equations





The Attempt at a Solution


Well I was trying to find the wavelength using the equation speed=Hz(Wavelength) but I don't have the speed. So I am really lost. If
anyone could guide me in some helpful equations I might need, because I have a quiz on this tomorrow

Are you sure the book/excercise you got the question doesn't give you the speed?

Yea positive. Checked it twice that's why I was confused.

Maybe I have to know the speed of sound through Air?
