Across
- 3. Consequence of a gap being smaller than wavelength.
- 5. Consequence of a gap being larger than wavelength.
- 7. Caused by superimposing waves that have been bent going through a gap, or around an obstacle.
- 11. Change of direction of a wave caused by interaction with a boundary.
- 13. Occur along the length of a wavefront, according to Huygens.
- 14. Bending of a wavefront as it passes close to an obstacle.
Down
- 1. Wave vibration limited to one orientation.
- 2. Consequence of a gap being equal to wavelength.
- 4. Change of direction of a wave caused by change of speed after moving across a boundary.
- 6. Equation linking angles of refraction and indices of refraction.
- 8. Ratio of speed of light
- 9. Polarised light.
- 10. A flat 2D boundary.
- 12. Wave vibration occurs in several orientations.
