rarefaction, and wavelength.

b. What is the equation for the speed of a wave? Identify each variable.

c. Fill in the blanks in the following paragraph to correctly describe the behavior of waves:
“A wave is a(n) that carries through space. Some waves travel through empty space. Other waves must travel through a material, also known as a . Waves transfer energy but not .”
