Across
- 2. the number of cycles or vibration
- 4. a change in the direction of a wave finds and obstacle or an edge
- 6. the lowest point of a wave
- 7. An observed change in the frequency of a wave when the source is moving
- 9. Allows light to pass trough, objects behind can be distinctly seen
- 12. the highest point of a wave
- 13. the distance from any pint on a wave to an identical point on next wave
- 14. the bending of a light ray as it passes from one substance to another one
- 15. a wave in which the particles on it move perpendicular
- 16. the throwing back by a body or surface of light, heat, or sound without absorbing it.
Down
- 1. a point of highest density in a longitudinal wave
- 3. a wave in which the particles of the medium vibrate parallel to the direction of wave motion
- 5. All of the frequencies or wavelengths of electromagnetic radiation
- 8. Note able to be seen through
- 10. the maximum that particles of a wave’s medium vibrate from their nest portion
- 11. Allows light but not detailed shapes
