1fundamental frequency
the vibration of lowest frequency aka first harmonic
2harmonics
vibration whose frequency are integral multiple of fundamental frequency
3overtone
harmonics except first harmonic
5density of air at ntp
1.29kg/m3
6elasticity
dimensions=Force/area (pressure)
7tempt and velocity
V directly proportional to ✓T
8velocity and density
V ~1/✓Density
9velocity and pressure
independent at pressure at constant temp PV=nrt if t in constant then PV=constant
