Across
- 1. the flow of energy through a material in the form of electric and magnetic fields
- 3. the change in direction of a wave passing from one medium to another caused by its change in speed. like a stick in water.
- 4. the amplitude of the resulting wave is equal to the sum of the individual amplitudes.
- 6. the distance a wave travels in a given amount of time
- 11. secondary waves and electromagnetic waves are examples of
- 12. the spreading of waves around obstacles
- 13. material
- 14. bouncing the wavefront back into the original medium. like a mirror.
- 15. the maximum displacement or distance moved by a point
Down
- 2. a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave.
- 5. the entire distribution of electromagnetic radiation according to frequency or wavelength
- 7. waves where the displacement of the medium is in the same direction as the direction of the travel of the wave. like a slinky.
- 8. the distance between identical points
- 9. the change in frequency of a wave in relation to an observer who is moving relative to the wave source.
- 10. the number of waves that pass a fixed point in a given amount of time
