A researcher immerses a sound detector in water to record the sounds emitted by the animals. The detector displays wavelength, frequency, velocity of propagation, and the distance at which the sound emitted by animals is produced. The investigator takes out the detector out of the water and records a sound. Which change in the variables mentioned allows the researcher to assure that the sound is transmitted by air and not by water? A. The wavelength. B. The frequency of the wave. C. The shape of the wave. D. The speed of the wave.
