-- What is the velocity of a wave that has a frequency of 2 Hertz and a wavelength of 2 meters?
Wavespeed = (frequency) x (wavelength)
Wavespeed = (2/second) x (2 meters)
Wavespeed = 4 meters/second
-- What is the frequency of a 5 meter wave that has a velocity of 1 m/s?
Frequency = (Wavespeed) / (wavelength)
Frequency = (1 m/s) / (5 m)
Frequency = 1/5 Hz (0.2 Hz)
