Which medium is MOST LIKELY a gas and why?
A
Medium C because it has the lowest density causing sound to travel the slowest.
B
Medium A because it has the highest density causing sound to travel the fastest.
C
Medium D because it has the second lowest density and the second highest frequency.
D
Medium B because it has an average density, causing the sound waves to travel at an average speed.
