Wave Speed Practice Problems
Use the equations to solve the following problems. v = f • λ v = d/t
4. A buoy bobs up and down in the ocean. The waves have a wavelength of 2.5 m, and they pass the buoy
at a speed of 4.0 m/s. What is the frequency of the waves?
5. Waves in a lake are 6 m apart and pass a person on a raft every 2 s. What is the speed of the waves?
6. One of the largest organ pipes is in the auditorium organ in the convention hall in Atlantic City, New
Jersey. The pipe is 38.6 ft long and produces a sound with a wavelength of about 10.6 m. If the speed
of sound in air is 346 m/s, what is the frequency of this sound?
7. A wave with a frequency of 60.0 Hz travels through vulcanized rubber with a wavelength of 0.90 m.
What is the speed of this wave?
