Question

In which medium does sound travel the fastest?
salt water
fresh water
air
cast iron

Answer 1

air

Answer 2

I'm terribly sorry, but sound should in fact travel the slowest in air. The speed of transmission is primarily a function of material density, and higher density materials tend to transmit mechanical vibrations more rapidly. Of your available choices, sound should propagate most quickly through iron.
