Calculate: Wave Velocity
Velocity = Wavelength x Frequency
V = λf
Where V = velocity (m/s)
λ = wavelength (meters)
f = frequency (hertz)
Hertz = 1/second or 1 cycle / second (hz)
Solve the following problems: Show the formula used, the problem set-up with units, and final answer.
1. The frequency of a slinky spring wave is 5 hertz with a wavelength of 0.8 meters. What is its velocity?
2. A wave is moving toward shore with a velocity of 5.0 m/s. If its frequency is 2.5 hertz, what is its
wavelength?
3. A tuning fork has a frequency of 280 hertz, and the wavelength of the sound produced is 1.5 meters.
Calculate the velocity of the wave.
4. The speed of light is 300 million m/s. The wavelength of FM radio waves is of 3.0 meters. What is
the frequency?
5. A jump rope is shaken producing a wave with a wavelength of 0.5 meters with the crest of the wave
passing a certain point 4 times per second. What is the velocity of the wave?
