2. What frequency sound has a 0.10m wavelength when the velocity of sound is 340 m/s
A=v/f=0.10
v=340
340/0.10 = 3400
3. A dolphin sends out a series of clicks to find out if there are fish nearby. The
velocity of sound waves in ocean water is about 1530m/s. If the echo is heard
.2 s after the dolphin made the sound, how far away are the fish?
4. Calculate the velocity of sound on a day when a 1500 Hz frequency has a
wavelength of 0.221 m.
