Across
- 4. What is the source of all waves
- 6. The number of to-and-fro vibrations in a given time
- 8. Vibration is in the direction of travel
- 10. Is described in terms of frequency, speed, amplitude, and wavelength
- 11. Is a change in frequency as measured by an observer due to the motion of the source or listener
- 14. The combined effect of two or more overlapping waves.
- 15. The time it takes for a complete vibration
Down
- 1. When light is incident on a rough surface it is reflected in many directions
- 2. is the propagation of a disturbance through a medium
- 3. Bending of light by means other than reflection and refraction
- 5. Vibration is at right angles (sideways) to wave travel
- 7. What refract when parts of the wave fronts travel at different speeds
- 9. Describes how fast the disturbance moves though the medium
- 12. The bending of a wave due to a change in the medium and/or speed of the wave
- 13. Occurs whenever successive impulses are applied to a vibrating object in rhythm with its natural frequency
