4. If the same wave in question #3 travels through water with the same wavelength, at what frequency will it be traveling? (speed of sound in water = 350 m/s)
(The speed of sound is 346 m/s. If a sound wave travels at a frequency of 55 Hz, what
would its wavelength be?)

6.A fisherman notices that one wave passes the bow of his anchored boat every 3
seconds. He measured the wavelength to be 8.5 meters. How fast are the waves
traveling?

8. A wave pulse is created in a slinky. It takes 1.2 seconds to travel the length of the
slinky. If the slinky is 8 meters long (1 wavelength), what is the speed of the wave?
