Sound is the form of energy that requires a medium for propagation. Sound cannot travel through a vacuum as there are no molecules present to be compressed and expanded. Learn more about what is sound @BYJU’S.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1] .
May 20, 2024 · Sound, a mechanical disturbance from a state of equilibrium that propagates through an elastic material medium. A purely subjective, but unduly restrictive, definition of sound is also possible, as that which is perceived by the ear. Learn more about the properties and types of sound in this article.
Dec 28, 2020 · Sound is a type of mechanical wave or an oscillation of matter. When a sound wave propagates through a medium, such as air, it does so by causing the air molecules to vibrate, which causes changes in air pressure. The speed of sound in air is around 343 m/s but can vary with temperature.
Jul 23, 2023 · What is sound? Sound is the energy things produce when they vibrate (move back and forth quickly). If you bang a drum, you make the tight skin vibrate at very high speed (it's so fast that you can't usually see it), forcing the air all around it to vibrate as well. As the air moves, it carries energy out from the drum in all directions.
Sep 21, 2019 · As you just learned, you hear when your ears process sound waves produced by an object. The object produces waves by vibrating. When an object vibrates, it pushes against the surrounding air. The vibrations cause the air to expand (called rarefaction) and compress.
What is sound? Sound is created by a vibrating object. Sound travels as a wave through a medium, for example, a liquid (such as water), a solid (such as the seafloor), or a gas (such as air). Therefore, sound does not exist in the vacuum of space. A sound wave is an example of a compressional or longitudinal wave .
What is sound? Sound: Feel the Vibration. Today we discussed sound and learned that sound travels in longitudinal waves, transmitting the vibrations of an object through a medium (solid, liquid, or gas) to our ears, where our brain interprets the pressure waves as various tones.
Sound is a longitudinal, mechanical wave. Sound can travel through any medium, but it cannot travel through a vacuum. There is no sound in outer space. Sound is a variation in pressure. A region of increased pressure on a sound wave is called a compression (or condensation).
The period of a sound wave is the time it takes for an air molecule to oscillate back and forth one time. The wavelength of a sound wave is the distance between two compressed regions of air. People get these mixed up because there's an alternate way to create a graph of this sound wave. Consider this.
