When a sound wave passes from air into a solid object, which of the following wave properties change?

-Frequency
-Wave Speed
-Amplitude
-Wavelength

all that apply

I already answered this once

When a sound wave passes from air into a solid object, two wave properties change: wave speed and wavelength.

1. Wave Speed: The speed of a sound wave is determined by the medium through which it travels. In general, sound waves travel faster in solids compared to gases (like air). So, when a sound wave enters a solid object, its wave speed increases.

2. Wavelength: The wavelength of a sound wave is the distance between two consecutive compressions or rarefactions in the wave. As the wave enters a different medium, the distance between these regions of high and low pressure changes. The wavelength of the sound wave becomes shorter in the solid object compared to its original wavelength in air.

It is important to note that the frequency and amplitude of the sound wave remain unchanged when passing from air into a solid object.

3. Frequency: The frequency of a sound wave represents the number of waves passing a given point per unit of time. It remains constant as the sound wave passes into a solid object. This means the pitch or musical note produced by the sound wave does not change.

4. Amplitude: The amplitude of a sound wave refers to its maximum displacement from equilibrium. It remains the same when transitioning from air into a solid object. So, the loudness or intensity of the sound wave does not change either.

To summarize, when a sound wave passes from air into a solid object, the wave properties that change are the wave speed (which increases) and the wavelength (which becomes shorter). The frequency and amplitude of the sound wave, representing pitch and loudness, respectively, remain unchanged.
