Answer: 0.68 meters
Explanation: The speed of sound at 54°C is approximately 348 m/s.
The formula to calculate the wavelength of a sound wave is:
wavelength = speed of sound / frequency
Substituting the given values, we get:
wavelength = 348 m/s / 512 Hz
wavelength = 0.68 meters (rounded to two decimal places)
Therefore, the wavelength of the sound is approximately 0.68 meters.
