Question

California sea lions communicate underwater at frequencies ranging from 500 to 4,000 hertz. The speed of sound in sea water is approximately 1,500 m/s. What are the approximate wavelengths of sound with which the California sea lions communicate?(1 point)
Responses

0.33 to 2.66 meters
0.33 to 2.66 meters

0.375 to 3 meters
0.375 to 3 meters

750,000 to 6,000,000 meters
750,000 to 6,000,000 meters

2,000 to 5,500 meters
2,000 to 5,500 meters

Answer 1

Wavelength λ = v/f. For v = 1500 m/s:
- at 500 Hz: λ = 1500/500 = 3.0 m
- at 4000 Hz: λ = 1500/4000 = 0.375 m

So the wavelengths are about 0.375 to 3 meters (answer: 0.375 to 3 meters).
