Sound waves follow a certain mathematical function that is based on what is called the "sine" in trigonometry. The attached article may be way too complicated to read through, but you can see what a sine wave looks like, and start to get an idea how a wave graph relates to something that is vibrating or oscillating.
When we first learn about sound waves we may think that sounds move through the air are following some kind of 'wavy' path; this is not the case. The wave that we draw on graph paper is a way for us to understand the layers of pressure that move toward us. Sound really moves more like countless expanding bubbles nestled inside one another, starting from the source. The bubbles are fronts of slightly higher pressure, followed by 'troughs' of slightly lower pressure.
Looking at a graphed sine wave, time is measured along the bottom, going toward the right. The up and down positions at any moment tell you what the relative pressure (air pressure, if you are considering sound moving through air) is.
The higher the frequency of waves (the more tightly packed the waves are-- the more peaks there are, say, in one second of time) the higher will be the pitch you hear. The farther up and down the peaks and troughs are, the louder the sound will be.
2nd Answer:
A sound that that produces sinusoidal displacement of air molecules with respect to time is a pure tone. That means it is a steady note with no overtones.
The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.
The main sound wave forms are sine waves, square waves, sawtooth waves, and triangle waves. Each wave form has its own unique sound characteristics and is used in different ways in sound synthesis and music production.
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
The shape of this sound is a sine wave, and that is what physicists call it. Musicians tend to call it the fundamental.
A transverse sound wave moves perpendicular to the direction of energy transfer, with particles vibrating up and down. It has properties like amplitude, frequency, wavelength, and speed, and can be represented by a sine wave.
The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.
It's hard to define a sound, but here's a try: A half-wave rectified sine sounds harsh and whiney. Not as sharp and jagged as a square wave, but not nearly as pure and smooth as a sine. The key is to realize that the half-wave rectified sine is a sine plus a significant load of harmonics, and wherever there is a lot of harmonic energy, we call it "total harmonic distortion". So the bottom line is, anything that isn't a pure sine, you would say it sounds "distorted".
By shifting the sine wave by 45 degrees.
For sound
Sine wave music is significant in sound therapy and relaxation techniques because its pure and simple sound can help induce a state of relaxation and calmness in the listener. The consistent and soothing nature of sine waves can help reduce stress, anxiety, and promote a sense of well-being.

A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
it would basicly be a sine wave that is declining simalarly to a fractal does, good life example is something bounceing up and down and slowing down till it stops or a sound that fades off.
The voice is not a sine wave.
A change in frequency is a change in pitch, in terms of sound. try to picture a sine wave in your mind. When you lower the frequency of the wave, it stretches the sine wave out (Which is how the pitch of the sound is lowered. I'm assume that you're question is about Audio.) For example, if you had a sound wave at 440Hz (And is aslo the musical note "A" on the center octave), and you changed its frequency to 329.63Hz, it would then sound lower in pitch (The musical note of "E") I hope that helps ;) ~Mitch
