Are you sure the temperature can change the frequency ?

Are you sure the temperature can change the frequency (assume the source frequency doesn't change)? The speed of sound may change, the wave length may change, but not the frequency.

It changes the density of water, of course, that changes the frequency. (无内容) - steven (0 bytes) 2014-04-08, 21:03:29 (745687)
