Across
- 3. distance between identical points
- 6. the throwing back by a body or surface of light, heat, or sound without absorbing it
- 7. interference Constructive interference occurs when the maxima of two waves add together
- 10. speed the distance a wave travels in a given amount of time
- 11. (compressional) wave Longitudinal or compression waves are defined as waves where the particle motion
- 13. the fact or phenomenon of light, radio waves
- 14. Effect The Doppler effect or Doppler shift is the change in frequency of a wave in relation to an observer who is moving relative to the wave source
Down
- 1. radiation the flow of energy at the universal speed of light
- 2. frequency waves that pass a fixed point
- 4. Spectrum the entire distribution of electromagnetic radiation according to frequency or wavelength.
- 5. a substance or material that carries the wave.
- 8. Wave motion in which all points on a wave oscillate
- 9. interference occurs when the maxima of two waves are 180 degrees out of phase
- 12. the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge
