An example of a purely longitudinal wave is a?
Sound wave is an example of a purely longitudinal wave. In a sound wave, the particles of the medium vibrate in the same direction as the wave is moving, creating compressions and rarefactions as the wave travels through the medium.
The wave pattern of smooth up and down curves is used to represent the way that a wave looks. What do the ups and downs mean when you are talking about sound waves?
When picturing the way sound travels in air, picture a big speaker cone. We've probably all seen one of these things at one time or another when a speaker cover has been removed and the speaker itself is exposed. The cone moves out and in to generate the sound. What's going on? When the cone moves out, it compresses air in front of it. All the gas atoms and molecules in front of the cone are smooshed (compressed) together and the "smooshed gas" (compression wave) moves out away from the speaker. It moves fast, too. Almost 3 ½ football fields a second. When the cone moves in, it creates a place of "unsmooshed" (rarified) gas in front of it, and the "unsmooshed gas" (rarefaction wave) travels out from in front of the speaker the way the compression wave did. A sound wave is an alternate series of compression and rarefaction fronts traveling in air. Comparing a sound wave to a wave traveling on water, the compression wave can be compared to the rising portion, the crest, of the water wave. The rarefaction wave can be compared to the dipping part of the water wave, the trough.
A sound wave has compressions that are very close to each other What is true about this sound wave?
The frequency of this sound wave is very near constant.
What is the result of a reflected sound wave?
The result of a reflected sound wave is obviously an echo.
How do you think the wave from a loud sound compares to the wave from a soft sound?
The amplitude (The height of the wave) of the wave increases as the sound gets louder.
If the pitch of the sound coming out from q speaker increases which is true about the sound wave?
If the pitch of the sound increases, the frequency of the sound wave also increases. This means that the sound wave is oscillating at a faster rate, creating a higher pitch.
What medium is a sound wave from a speaker?
Air is the medium.
How does sound travel from a loud speaker to your ear?
Sound leaves the speaker in the form of a wave, through the air, and enters your year, where the eardrum picks up the vibrations of the wave and sends a signal to your brain which interprets the vibrations as sound.
When a sound wave is reflected you hear a?
When a sound wave is reflected, you might hear an echo. The reflected sound wave can arrive at your ear slightly after the direct sound wave, creating a delayed repetition of the original sound.
The echo of a sound wave is due to what of the sound wave?
The echo of a sound wave is due to the reflection of the sound wave off a hard surface, such as a wall or a cliff. The reflected sound wave travels back towards the source, creating the perception of an echo.
An example of a purely longitudinal wave is a?
Sound wave is an example of a purely longitudinal wave. In a sound wave, the particles of the medium vibrate in the same direction as the wave is moving, creating compressions and rarefactions as the wave travels through the medium.
What is an example of electrical energy changing into sound energy?
An example of electrical energy changing into sound energy is when an electric current passes through a speaker system. The electrical energy powers the speaker's electromagnet, which causes the speaker cone to vibrate and create sound waves in the air.
Why is sound a longitudinal wave?
Sound is a longitudinal wave because the particles in the medium vibrate back and forth in the same direction that the wave is traveling. This causes areas of compression and rarefaction, creating the sound wave that we hear.
How can an underwater bubble be collapsed using a sound wave?
An underwater bubble can be collapsed using a sound wave by creating a high-intensity sound wave that causes the bubble to shrink and eventually collapse due to the pressure changes caused by the sound wave.
How does a audio speaker work?
An audio speaker works by converting electrical signals into sound waves through the movement of a diaphragm. When an electric current passes through a coil of wire in the speaker, it creates a magnetic field that interacts with a permanent magnet, causing the coil to move back and forth. This movement of the coil vibrates the diaphragm, creating sound waves that we hear as sound.
What is the movement of sound from one location to another?
Sound moves through a medium, such as air, by creating vibrations. These vibrations cause particles in the medium to compress and expand, creating a wave that travels from the source of the sound to the listener. The sound wave carries the energy of the sound from one location to another.
How can I create a sound wave from audio?
You can create a sound wave from audio by converting the audio signal into an electrical signal using a microphone, then amplifying and transmitting it through a speaker to produce sound waves that can be heard.
