Components of a Sound Wave
Components of a Sound Wave
?A: Amplitude ???: wavelength ? f: frequency
??=??f
? Pitch (high/low) ? Volume (loud/soM)
How fast does sound travel?
/v B ?=
Bulk modulus
Density
? B depends on pressure and volume ? But we can re-?write this in terms of only one
variable
The speed of sound in air at a constant temperature is a constant.
C331 1 273 T
v = +
v at room temperature (20°??) is about 343 m/s
