Final answer:
The wavelength of a 262 Hz middle C underwater is approximately 5.725 meters when the speed of sound in water is 1500 m/s.
Step-by-step explanation:
To find the wavelength of a 262 Hz middle C underwater, we can use the formula that relates the speed of sound, frequency, and wavelength, which is v = f × λ (where v is the speed of sound, f is the frequency, and λ is the wavelength). Given that the speed of sound in water is 1500 m/s, and the frequency is 262 Hz:
λ = v / f
λ = 1500 m/s / 262 Hz
λ = 5.725 m
Therefore, the wavelength of a 262 Hz middle C under water is approximately 5.725 meters.
