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
