To add to all these confusion:
If speed of sound travels FASTER in MORE DENSED air, then why is it slower if you are moving from a warmer to a colder place, assuming you are in level flight. Isn't colder air denser than warmer air. The question: Is speed of sound faster/slower in colder air.
I know the speed of sound is a function of temperature. So how does the density effect it if sound travels faster in denser air.
formula Mach 1= 39*square root of K
K=temperature in Kelvin
