A student tries to rank sound speed in two materials using density alone. Why is that incomplete?
A
Density controls pitch but not speed.
B
Sound speed depends on both elasticity and density, so density alone is not enough.
C
Sound speed depends only on frequency, so material properties do not matter.
D
A denser material can never transmit sound.
