Homework Statement
Sorry, it's not an actual problem, it's just a statement I don't understand from my text - "The density of water vapor is less than that of dry air. Therefore, the higher the humidity (that is, the more water vapor there is in the air), the lower the density of the air. For this reason, sound travels through the air more rapidly in damp weather than in clear weather."
But why?
Homework Equations
/ 3. The Attempt at a Solution [/B]Earlier we learned that in solids, denser materials make for faster movement of sound through them, because the molecules are closer so they can transmit the energy faster. Why wouldn't it be the same for air? I think it would matter more for air because the molecules are even farther apart.
