Question

which wave property determines the loudness of a sound? frequency amplitude wavelength speed

Explanation:

The amplitude of a sound wave refers to the maximum displacement of particles in the medium through which the sound is traveling. A larger amplitude means more energy is being carried by the wave, which results in a louder sound. Frequency determines pitch (how high or low a sound is), wavelength is related to frequency and speed (\(v = f\lambda\), where \(v\) is speed, \(f\) is frequency, and \(\lambda\) is wavelength), and speed is how fast the wave propagates through the medium.

Answer:

amplitude
