Across
- 2. Change in direction of a wave passing from one medium to another caused by its change in speed
- 4. Waves where the displacement of the medium is in the same direction as the direction of the travel of the wave
- 10. Maxima of 2 waves are 180 degrees out of phase
- 12. Radiation that has both electric and magnetic fields and travels in waves
- 13. Spreading of waves around obstacles
- 14. Distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire
- 15. Any material substance which can propagate waves or energy
Down
- 1. Range of frequencies of electromagnetic radiation and their wavelengths
- 3. Motion in which all point on a wave oscillate along paths at right angles to the direction of the wave's advance
- 5. Maxima of 2 waves add together so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes
- 6. Change in direction of a wavefront between two different media, bouncing the wavefront back into the original medium
- 7. Distance a wave travels in a given amount of time
- 8. Apparent differences between the frequency at which sound or light waves leave a source and reach an observer
- 9. Maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
- 11. Number of waves that passed a fixed point in a given amount of time
