Physics Wavelength

Question

Find speed v𝑣 if the distance traveled is one wavelength λ𝜆 and the time of travel is the period T𝑇(which equals 1/frequency).

Answer 1

Distance = velocity times the time, D = V x t. In this case D = λ (wavelength), and t = T (time to travel one wavelength or one cycle), so V = λ / T.
