Physics ch 7 Waves and Sounds Flashcards

Propagation speed (v)

v= f ?
f: frequency (Hz)
?: wavelength

Period (T)

T= 1/f

Angular frequency (?) rad/sec


?= 2?f=2?/T

Speed of sound (v)

v= ?B/?
B: bulk modulus (medium resistance to compression)
?: density of the medium

The speed of sound is fastest in a ................. with ...........
density, and slowest is very.............. ................

solid, density
