Sound waves travel faster in humid air because humidity would decrease the density of the air. As density decreases then speed of sound would increase as speed is given as c = ./ P/d ./ is the square root symbol. d is the density and P the pressure. Pressure change wont change the speed of sound since P/d remains constant.
Some advantages of air travel are getting to your destination faster, allowing us to travel over sea, and help us avoid traffic. :D hope this helped!
It will increase.
Sound travels slowest through d) wood. Wood is a solid material and sound waves travel slower in solids compared to liquids and gases like air, glass, and water.
