Sound Waves
Sound waves are a mechanical oscillation of pressure. It is a series of vibrations that can be heard.

An increase in the frequancy of sound waves will correspond most directly to an increase in what?
Pitch
There is a few ways this happens. Lower instruments (i.e. tubas, bass clarinets, euphoniums) sound travels slower than say a flute, trumpet, or clarinet, therefore if lower instruments don't neccessarily play ahead of the tempo (not rushing but keeping tempo rather than following it) will sound behind but the closer you are to the band the more together it will sound. The football field might have affect too depending where are you sitting. if there is steep bleachers and there very tall, you are supposed to aim towards the pressbox so sound will hit the pressbox and have to travel to you below it. If the bleachers are laid back and kind of tall it will hit almost at the same time. If your sitting by the field it will sound a little more together if the lower instruments are keeping tempo.
What does the high frequency of a sound wave determine?
The frequency of a sound wave determines the pitch. So if there is high frequency it means that the sound will also be high pitched. If it is low frequency that means the sound will be low pitched.
What enables sound to travel from a boat to a submarine?
Sound waves propagating through the water do.
What do water waves light waves sound waves transfer?
Energy is transferred by all these three types of waves. The media for these three are water, space and air respectively.
Do sound waves always travel in straight lines explain?
No, Sound is a pressure wave not a linear wave, the waves radiate spherically from their point of origin.
Also as a pressure wave, it travels in a medium and if that medium is moving the sound wave propagation can be modified by that movement (bent).
They also behave like sea waves impinging on a headland and can be bent round objects in their path in complex ways.
Is heat matter Are sound waves matter Is water matter Is bacteria matter Is oxygen matter?
Yes they all are matter because every thing in the world is made out of matter. Also because heat is a solid, water is a liquid, bacteria is a liquid, and oxygen is a gas.
Why cant Sound waves in outer space cannot travel in outer space because?
No air. Sound is vibration is something- most commonly air, but sometimes water, metal, etc. There is no air in outer space to be vibrated.
What is the sound frequency of a chicken?
Most living beings, such as chickens and humans, don't produce a single sound frequency; rather, the sound emitted is a mix of frequencies. That's why the sounds of each creature sound different.
Sound is produced by vibration in the air. For example, when you speak your vocal cords vibrate, causing a sound. Your ears sense the vibration and tell your brain about the change in environment.
How does sound travel in solid liquid and in gas . explain?
Sound travels by particles (such as atoms or molecules) bumping into other particles, thus transferring the energy, in form of a sound.
How can I modify my MICROPHONE to filter background noise?
There are certain features on editing softwares such as Audacity or Logic Pro X that can help with this, but I would suggest using an actual filter, purchase on online, that surrounds the microphone! This will work the best.
What type instrument produce transverse wave?
If you mean sound waves, the only type of sound waves that can travel through air (or any gas, for that matter) is longitudinal waves.
What is a form of electromagnetic energy is made up of streams of photons?
An electromagnetic wave, or electromagnetic radiation.
Is the string a better carrier of sound than air?
Yes, solids transmit sound better than gases because their molecules are closer together.
Question is to be corrected as to find the velocity of the sound waves
Formula for velocity of the wave = frequency x wavelength
Given frequency = 262 Hz and wavelength = 1.3 m
So velocity = 262 x 1.3 = 340.6 m/s
What does it mean when sound waves are reflected of canyon walls?
It means that the sound wave goes toward the canyon wall, and then a wave carrying part of the energy comes back from the canyon wall. The remaining energy will be absorbed or will pass through.
Is Sound energy is a type of mechanical energy?
Simple Version:
The energy in a sound wave is mechanical, being both kinetic and potential energy associated with the air.
Explained:
Just as in a vibrating spring, the medium (air) 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. (The air is compressed and expanded in a sound wave.)
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.
The force of gravity between two objects is proportional to their masses and inversely proportional to the square of the distance between them.
The intensity increases by a factor of 4

What are sound waves that bounce back and forth?
An echo is a distinct repetition of the original sound. The reflection of sound from a cliff face for example. A flutter echo is s separate class of echoes (according to the acousticians), and will be experienced in a relatively bare room, where an impulse sound such as a clap will be heard multiple times, but quickly decreasing in volume. Your bathroom might be a good place to try for one.
In a concert hall (or a lecture room), an early reflection of the sound will not be perceived as a separate signal, but will aid in better understanding of the source, and may in fact be the source of the majority of the signal at that point. The source of the sound will still be seen as that from which the signal was first heard. Our ears have some truly remarkable properties.
Reverberation is the sustained repetition of echoes of the original sound. A small amount of reverberation is a desired feature in a concert hall, as it adds warmth to the sound. But excessive reverberation; as in many cathedrals for example; seriously interferes with the understanding of speech. It suits organ music very well.
