Across
- 4. A wave that requires a medium through which to travel
- 8. The lowest point on a wave
- 9. The bouncing back of a ray of light, sound, or heat when the ray hits the surface that it does not go through
- 10. A wave in which particles of the medium vibrate parallel to the direction of wave motion
- 11. The combination of two or more waves of the same frequency that results in a single wave
- 12. The number of waves produced in a given amount of time
- 14. A wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
- 16. The bending of a light ray as it passes from one substance to another one with different a density
Down
- 1. An observed change in the frequency of a wave when the source or observer is moving
- 2. The maximum distance that the particles of a wave’s medium vibrate from their rest position
- 3. The amount of time it takes for a full wavelength to pass
- 5. The highest point of a wave
- 6. The distance from any point in a wave to an identical point on the next wave
- 7. A change in the direction of a wave when the wave finds an obstacle or edge, such as an opening
- 8. A wave in which the particles of the medium move perpendicular to the direction of the wave traveling
- 13. The substance through which a wave can travel
- 15. The ability to do work
