In the context of wave functions, how does increasing the frequency $f$ of a wave affect its wavelength $\lambda$, assuming the wave speed $v$ remains constant?

Which statement is true if you increase the $f$ (frequency) of a periodic wave?

If a wave is traveling through a medium labeled $x$, what can be inferred about the properties of $x$?
