What two properties of a material affect the speed of sound in the material?
a) Specific heat and density.
b) Density and volume.
c) Density and stiffness.
d) Buoyant force and density.
Homework Answers
The two properties are density and stiffness(option 'c').
If stiffness of the material is increased, speed of sound in the material increase.
If density of the material is decreased, speed of sound in the material increase.
