When a sound wave passes from air into a solid object, which of the following wave properties change?
-frequency
-wave speed
-amplitude
-wave length
Can be more than one
wave speed, wave length and (usually) amplitude. There will be both reflected and transmitted waves
When a sound wave passes from air into a solid object, the following wave properties change:
1. Wave speed: The speed of sound wave changes when it passes from air into a solid object. The speed of sound is generally faster in solids compared to air. This change in wave speed can be attributed to the difference in density and elasticity between air and the solid object.
2. Amplitude: The amplitude of the sound wave can also change when it passes from air into a solid object. The amplitude refers to the maximum displacement of the particles in the medium as the sound wave passes through. When the sound wave enters a solid object, the particles in the solid medium are closely packed, which can lead to an increase in the amplitude.
3. Frequency: The frequency of the sound wave remains unchanged when it passes from air into a solid object. The frequency represents the number of complete oscillations a particle in the wave performs per unit of time. As long as the medium does not significantly affect the movement of the particles, the frequency remains constant.
4. Wavelength: The wavelength of the sound wave can change when it passes from air into a solid object. The wavelength represents the distance between two successive wave crests or troughs. In a solid medium, due to the higher wave speed, the wavelength may decrease compared to the wavelength in air. However, this change is dependent on the specific characteristics of the solid object.
In summary, when a sound wave passes from air into a solid object, the wave speed, amplitude, and wavelength can change, while the frequency remains the same.
