- 17.2: Sound Waves
28 Ιουλ 2022 · The sound wave carries energy and keeps traveling until it loses energy. Sound requires a medium to propagate. It can travel through air, water, wood, glass, or metal. Unlike light, sound cannot propagate in a vacuum since there are no particles to transmit the wave.
In physics, sound energy is a form of energy that can be heard by living things. Only those waves that have a frequency of 16 Hz to 20 kHz are audible to humans. However, this range is an average and will slightly change from individual to individual.
In this section, we examine the quantitative expression of energy in waves. This will be of fundamental importance in later discussions of waves, from sound to light to quantum mechanics. Energy in Waves. The amount of energy in a wave is related to its amplitude and its frequency. Large-amplitude earthquakes produce large ground displacements.
23 Ιουλ 2023 · Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.
On the atomic scale, sound is a disturbance of atoms that is far more ordered than their thermal motions. In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects (Figure 17.2.2 17.2. 2).
Acoustics: the study of sound waves. Sound is the phenomenon we experience when our ears are excited by vibrations in the gas that surrounds us. As an object vibrates, it sets the surrounding air in motion, sending alternating waves of compression and rarefaction radiating outward from the object. Sound information is transmitted by the ...
