Find the wave length

Khemkhajon

1. The problem statement, all variables and given/known data
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.

2. Relevant equations



3. The attempt at a solution
Well I was trying to find the wavelength using the equation speed=Hz(Wavelength) but I dont have the speed. So Im 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 thats why I was confused.

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