Final answer:
To find the frequency of a sound wave in water with a wavelength of 1.5 m and a speed of 1500 m/s, use the equation v = f × λ to get a frequency of 1000 Hz (option A).
Step-by-step explanation:
To determine the frequency of a sound wave when you know the speed of sound in the medium and the wavelength, you can use the formula v = f × λ, where v is the speed of sound, f is the frequency, and λ (lambda) is the wavelength. In the given problem, the speed of sound in water (v) is approximately 1500 m/s and the wavelength (λ) is 1.5 m. To find the frequency (f), you rearrange the equation to f = v / λ and substitute the values:
f = 1500 m/s / 1.5 m = 1000 Hz
Therefore, the frequency of the sound wave is 1000 Hz, which corresponds to option A.
