Across
- 3. light bouncing off an object in the same angle
- 7. Wavelength x Frequency
- 9. the range of electromagnetic radiation and frequency
- 12. waves where the particle motion is in the same direction in which the wave is propagating
- 13. one wave cancelled by the other
- 14. gamma rays, microwaves, radio waves
Down
- 1. light bending through a medium
- 2. two waves added together
- 4. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
- 5. change in frequency of a wave in relation to an observer who is moving relative to the wave source.
- 6. object where light can pass through
- 8. waves going through an opening
- 10. how many waves in a amount of time
- 11. velocity/frequency
- 15. maximum displacement of a wave
