Physics - Sound uses molecules


Expert: Expert - 11/6/2009

Question
sound has no mass right? why cant it travel the same speed as light?

Answer
Sound consists of organized vibrations of molecules -- ie, particles with mass. These vibrations propogate at a few hundred kilometers per hour, as each group of molecules pass on their vibratons to the next group. In that sense, sound DOES have mass.
