Explanation:

1. A wave transports energy from one place to another.
2. Wavelength is the distance between one point on a wave and the same - type point on the next wave.
3. Frequency is measured in units called Hertz.
4. Refraction is the change in direction of a wave when it travels from one material to another.
5. Diffraction is the bending of waves around objects.
6. Intensity is measured in units called decibels.
7. Pitch is how low or high a sound seems.
8. Reverberation is repeated echoes.
