Predict the order of materials from slowest to fastest for sound wave travel.

• Solid, Liquid, Gas

• Gas, Liquid, Solid

• Liquid, Gas, Solid

• Gas, Solid, Liquid

How does the density of a medium affect the speed of sound waves?

• Lower density always means faster sound

• Higher density can mean faster sound if the medium is solid

• Density does not affect sound speed

Select the statement that is true about sound waves.

• Sound waves are transverse waves.
