Speed of sound, frequency, and wavelength Elia Martinez

Vocabulary

Frequency ~ the rate at which a vibration occurs that constitutes a wave;usually measured per second. (Merriam Webster.com)

Wave Length ~ measured in the direction of propagation of a wave, between two successive points in the wave that are characterized by the same phase of oscillation.(Dictionary.com)

Pitch ~ the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. (Wikipedia.org)

Adjacent compressions ~ the distance between two corresponding points on adjacent waves. (ck12.org)

compressibility ~ the capacity of something to be flattened or reduced in size by pressure. ( Wikipedia.com)

simple harmonic motion ~ constant amplitude in which the acceleration is proportional and oppositely directed to the displacement of the body from a position of equilibrium (Merriam webster. com )

Thermal motion is caused by the amount of heat that is present near an atom. Sound vibrations are intense movements of atoms that are strong enough for the human ear to hear.

Frequency does not change when it passes through one medium because frequency is how fast it is going, so that won't affect anything as long as it still gets to the other medium.

17.2 talks about what the speed of sound relies on, which is what causes the speed of sound to change with different things. Speed depends on medium, which can be a solid, liquid, or gas. It also depends of frequency. Frequency almost always remains the same, even if the sound changes, the frequency is still the same from where it came from.
