I would expect any movement of matter to cause some sound.

amplitude

The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound.

The auditory canal allows sound to get to the eardrum.

By the frequency. The higher the frequency, the shorter the wavelength. The lower the frequency the longer the wave length.

C= L * f

C = Time in milliseconds (343 m/s @ 20 degrees C , L= Wave Length or Lambda in meters and f= frequency in Hertz

A little algebra and you have;

L= C/f

Example; 343 m/s / 100 Hz = .343 meters

Frequency is a function of time, cycles per second. Time is the reciprocal of frequency

(1/f= T).

Something must vibrate, to make the air (or whatever else the sound travels through) vibrate.

The curtains provide attractive sound deadening so that it doesn't echo in the theater. Some theaters just use other sound absorbing methods but the curtains are something of a hold-over from the older theaters where plays and concerts were performed in the past and have a nice appearance.

The loudness of a sound is related to how much energy is transmitted to the air. Clapping your hands transmits a small amount of energy. Detonating a stick of dynamite transmits MUCH more energy. The amplitude of the sound wave is much greater, and the noise, louder.

The four basic wave interactions are: wavelength, trough, crest, and amplitude.

they are different by the way they behave and the way it is different is one behaves like they should and the other one behaves bad.

Often both.

The main drawback of SONAR Technology (but will not affect anything in a small-scale setting) is the DOPPLER EFFECT. Your SONAR TX/RX must have to compensate from the DOPPLER EFFECT once your origin or destination is starting to move. But if we're talking about a stanionery source AND destination the DOPPLER EFFECT will have no cause/effect whatsoever.

Also, just to bring it out, the environment wherein your SONAR is working is a big consideration regarding its performance.

Hope it helps.

No. Loud sounds from near a school are unlikely to break the glass. They would have to be extremely loud.

Sonar

the interaction between sound waves is called interference.

No, you can not produce sound in a vacuum. Sound wave needs medium (for example air) to travel unlike electromagnetic wave which can travel through empty space.actually, sound wave does not propagate itself rather it needs a medium by which sound particle can transfer there energy from one place to other, so it seems like moving.

for eg. when u throw a stone in water ,some ripples form in water they seems to moving but not. like this sound propagate.

hence it requires medium

I would guess that there is no SIGNIFICANT amount of echo, because they were designed that way on purpose. The way this can be done is by covering walls and floors with materials that absorb most sound.

Sound waves are waves of energy created by the vibration of a source (vibrating phone, vocal cords, etc.) that travel through a medium (air, water, solids). This means that the plant will get extra energy aside from sunlight that will make it grown at faster rates. It depends how fast those sound waves travel (frequencies) and how loud the sound waves are. Hope that answers your question!

The energy in a sound wave is both kinetic and potential.

Just as in a vibrating spring, the medium has mass and moves and so moving mass is kinetic energy.

Just as in the spring there is compression and rarefaction, so there is elastic potential energy.

In fact, these two are equal, potential energy = kinetic energy, just like a spring.

Just like in a vibrating spring, the total energy is constant and equal to the average kinetic energy plus the average potential energy.

A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.

No

Echoes of sound and images in a mirror involves sound waves and light waves respectively being reflected off a surface.
