wavelength
the distance between two troughs or two crests
amplitude
the distance (vertically) between a trough and a crest
period
how many cycles occur in one second (time/cycles or 1/f) measured in seconds
frequency
how many times something happens in a set time (1/period or velocity*wavelength) measured in Hz
node
a point in a standing wave with the least amount of movement up and down (found between bumps)
antinode
the troughs and crests of a standing wave, move up and down the most
velocity of sound in air
340 at 0ºC, 343 at room temp
velocity
the speed of something (v=f*wavelength) measured in m/s, convert wavelength to m by dividing by 100
loudness
how we percieved amplitude, measured in dB, +10dB seems to double, -10dB seems to halve
