1. The frequency of a particle's vibration is greater than yhe frequency of the waves. 2. Diffraction is the changing of the direction of the waves. 3. Amplitude is the height from the middle of the wave to the trough. 4. The period and frequency of a wave have the same value. 5. Wave speed is directly proportional to the period of the wave. 6. Wave velocity depends on the properties of the medium in which it is traveling. 7. The distance between two successive troughs is called wavelength. 8. A wave is composed of oscillations that move with the particles being carried with them. 9. The incident rays that strike a boundary cannot bounce and cannot be transmitted. 10. High-frequency waves have long wavelength.
