Sound Waves

"Radio" is the name we give to a section of the electromagnetic spectrum, so it can

include whatever wavelengths we decide to use that name for.

Radio is generally considered to be everything in the electromagnetic spectrum with

wavelengths of one millimeter or longer, corresponding to any frequency up to 300 GHz.

Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.

The ultrasonics used in various applications like in Industrial , medical ,etc.

# INDUSTRIAL APPLICATION:

1. ultrasonics are used for soldering and drilling purposes .

2. ultrasonics are used for cutting and welding purposes also .

3. ultrasonics are used to emulsify immiscible liquids like mercury and water.

4. ultrasonics are used for cleaning of tiny objects like watches etc .,

5. ultrasonics are also used in the sterilization of water and milk.

#MEDICAL APPLICATION

1.Ultrasonics waves are used for relieving neuralgic and rheumatic pain .

2.Ultrasonics waves are used to destroy dangerous tissues in the human bodies .

3. Ultrasonics are used in extraction of broken teeth without pain .

4. Ultrasonics waves are used to find the velocity of blood flow and the movement of heart in human body also .

water Dense solid objects

Same way it travels through air;

each molecule vibrates the one next to it

which then vibrates the one next to (the new it)

and so-on.

No, if that were true, every time you heard thunder you would feel a huge wind. The movement of air particles cause the sound to propagate (go through the air), but the particles themselves don't really go anywhere (except where they would have gone anyway in silence). It's analogous to waves on the water: If you drop a rock into a pond, you can see the resulting waves going out in growing circles, but the water molecules themselves are moving only up and down. A simple experiment that shows this is putting a small air-filled ball on a pond and dropping a rock into the water near it. Instead of the ball being carried away by one of the resulting waves, it moves only up and down.

Ultra Sound

First you convert the sound into a modulated electric current using a microphone, then you convert the modulated electric current into a visible pattern using an oscilloscope.

A subjective measure of sound is whether something is too loud, or too soft. A scientific measure of sound is gauged in the decibel level of the noise.

A wind chime has several objects which produce a "chime" when they strike each other. When a wind chime is left hanging freely, the wind makes the objects move and they strike each other to produce a chiming sound.

The amplitude (The height of the wave) of the wave increases as the sound gets louder.

That would depend on many factors. Length, thickness, density, resonance....too many factors to take a stab at an answer.

1. the waves spread out over a larger area
2. the waves are absorbed by the medium as they pass through it
3. the waves are being scattered by irregularities in the medium and don't all proceed forward
4. etc.

1. Sound waves enter your outer ear and travel through a narrow passageway called the earcanal, which leads to your eardrum. Your eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in your middle ear. These bones are called the malleus, incus, and stapes.

Particles. They can't travel through a vacumm

Sound waves can be stopped or absorbed by dense materials such as walls, buildings, or soundproofing materials that prevent the waves from passing through. Additionally, sound waves can be reflected or refracted if they encounter surfaces that are not conducive to their propagation.

When you vibrate you create a sound all sounds are created by vibrations.

The sound that is produced when a water glass is struck or its lip is rubbed is caused by the vibration of the glass and its effect on the surrounding air. As more or less water is added, the amount of glass that can freely vibrate changes.

Sound curtains can absorb incoming sound waves, lessening the noise from the exterior of a room and deadening the sound coming from inside the space. While curtains may not be able to entirely block out loud noises, a properly mounted sound curtain should drastically reduce outside noise. One of the major advantages of sound curtains, air compressor screens, and portable sound control screens is that you can create a quiet, peaceful space even if you live in a noisy area near a busy road or train tracks. Another great advantage of sound curtains is that they are a far less expensive option than installing metal walls or other sound-blocking mechanisms. A disadvantage to sound curtains is their heavy appearance, which may block out any natural light coming from outside the room. However, at Goff’s, customers can benefit from their unique fan folding sound curtain design, which allows you to adjust the level of sound reduction and appearance of your curtains.

Choose from the various mounting options at Goff’s, which include ceiling, wall and freestanding sound curtains. Contact them today at 800-763-1538 to learn more about their effective sound reducing products.

Sound waves are propagated as compression waves in air (and in other gases). They will be produced by any object vibrating at appropriate frequency. As far as humans are concerned, we can hear frequencies from about 25 HZ up to 15 kiloHz, though the upper register gets less efficient as you age. For music or speech transmission we use a loudspeaker which is some sort of diaphragm actuated by a moving coil which responds to electrical signals in this frequency range, and the diaphragm produces the compression waves simply by moving in and out. Sound waves travel at about 720 mph in air at normal temperature and pressure.

more like vibrations that's more like how they move because vibrations move throught matter and then so does sound
