Across
- 3. in the direction of propagation of a wave that strikes the boundary between different mediums.
- 9. disturbances from place to place in a regular and organized way
- 12. selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force
- 13. between - crests of a wave, especially points in a sound wave or electromagnetic wave.
- 14. in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance.
- 15. of waves around obstacles
- 16. displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position
- 17. consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
Down
- 1. of waves that pass a fixed point in unit time
- 2. interval between two successive repetitions.
- 4. point at which all radiation coming from a single direction and passing through a lens or striking a mirror converges
- 5. in direction of a wave passing from one medium to another caused by its change in speed.
- 6. motion repeating itself
- 7. waves overlap in such a way that they cancel each other out
- 8. two waves overlap in such a way that they combine to create a larger wave
- 10. waves that are created as a result of vibrations between an electric field and a magnetic field.
- 11. through which a wave can propagate
