Across
- 1. a superposition of two or more waves that produces an intensity equal to the sum of the intensities of the individual waves
- 3. the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
- 4. refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium
- 6. the highest point of a wave
- 7. the lowest point of a wave
- 10. a line in space that matches the direction of the flow of radiant energy
- 11. a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
- 14. the distance from any point on a wave to an identical point on the next wave
- 16. the maximum distance that the particles of a wave’s medium vibrate from their rest position
- 17. a wave in which the particles of the medium vibrate parallel to the direction of wave motion
- 18. the combination of two or more waves that results in a single wave
- 19. an observed change in the frequency of a wave when the source or observer is moving
- 20. is a disturbance that wave carries energy through matter or space
Down
- 2. The electromagnetic spectrum consists of waves at all possible energies, frequencies, and wavelengths
- 5. a wave that requires a medium through which to travel
- 8. the number of cycles or vibrations per unit of time
- 9. a superposition of two or more waves that produces an intensity equal to the difference of the intensities of the individual waves
- 12. a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
- 13. a physical environment in which phenomena occur
- 15. a unit or quantum of light; a particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy
