A dolphin can typically hear sounds with frequencies up to 150 Hz. What is the speed of sound in water if a wave with this frequency has a wavelength of .02m?
A. 7,500 m/s
B .00013 m/s
C. 3 m/s
D. 3 Hz
E. Other
To determine the speed of sound in water, we can use the formula v = fλ, where v represents the speed of sound, f represents the frequency, and λ represents the wavelength.
In this case, the dolphin can typically hear sounds with frequencies up to 150 Hz, and it is given that the wave has a wavelength of 0.02 m.
Plugging these values into the formula, we have:
v = fλ
v = 150 Hz * 0.02 m
v = 3 m/s
Therefore, the speed of sound in water for a wave with a frequency of 150 Hz and a wavelength of 0.02 m is 3 m/s.
The correct answer is option C: 3 m/s.
