Homework Statement
I am so confused with speed of sound. would sound travel faster in cold or warm air?
if you put mathmatical equation in, v= 331 + (0.59Tc) then it would travel faster in warm air.
but another theory says that sound travels faster in denser medium and cold air is denser than warm air, hence it travels faster in colder air. it it true?
And at night over water we can hear sound clearly on shore than during the day because of colder air during night and over water, as cold air is dense, molecules can bump into each other better as they are closer, makes it travel faster? or the speed of it has nothing to do with it? would the answer be just (it travels better because it is denser)?
please help me out thanks
