$$\lambda = {v \over f}$$If frequency $f$ is constant, and the wavelength $\lambda$ is the same, what will the velocity be?

Whats the exact answer please ? Do inform .Thank You !

anonymous · Answer

If medium a and medium b have the same frequency and wavelength, the velocity in each will be the same. 

If you think about it, I'm sure you can figure it out.
