Answer:
C. Speed
Step-by-step explanation:
Density differences in different materials are able to change the speed of a wave.
- Wave speed is dependent on the frequency and wavelength of a wave.
- As a wave travels from one medium to another, the speed of the wave changes.
- Speed of a wave is medium dependent.
- The denser a medium, the slower the speed of waves will be be.
- A less dense medium will have waves traveling through faster.
