Waves & Optics / Waves - 3 min

A periodic wave travels through a medium at a constant speed:

v=4\,\mathrm{m\,s^{-1}}

Its frequency increases from $4\,\mathrm{Hz}$ to $8\,\mathrm{Hz}$ while its speed stays the same. What is the new wavelength?

Assumptions

Assume the wave speed remains constant as the frequency changes.
