Wave Velocity Worksheet
1. Rank these waves based on the velocity of the waves from greatest to least. Place the wave that is
moving faster first, and the wave that is moving slowest last. If waves have the same velocity,
rank them as equal. λ = wavelength and f = frequency

Explain your reasoning:
2. A wave with a length of 1.5 meters vibrates at a frequency of 300 Hz. What is the speed of the wave?
3. What is the speed of the wave in problem 2 if you double the frequen
4. What happens to the wavelength of the wave in problem 2 the frequency is cut in half? How do you
know?
5. The school’s star basketball stars wants to train enough to have a heart rate of 70 beats per minutes.
What is the period of one heartbeat?
6. A primary wave from an earthquake traveled 6.1 km/s. If the frequency of the earthquake’s wave is 80
Hz, what is the wavelength? How many wavelengths would it take to travel 800 km?
7. Radio waves travel at the speed of light, 300,000 km/sec. What is the frequency of a radio wave with a
wavelength of 30 meters?
8. Mile and Ike wiggle a giant slinky up and down. The vertical distance from the crest to a trough is 30
cm, the frequency is 15 Hz, and the horizontal distance from crest to trough is 45 cm. Draw a scaled
representation of this wave. Then determine the amplitude, period, frequency, wavelength and wave
speed?
