Properties of Waves

2. At point of incidence, all reays lie on the _____ plane.
5. The interference that leads to the canceling out of the waves to give zero Resultant.
8. The wave moves back along its _____ course.
10. Angle of incidence and angle of reflection are ____.
11. Remains constant during Refraction.
12. A light produced by passing an ordinary light through a polarizer.
13. A transverse waves which vibrates in only one plane.
14. The wave that travels towards the surface is the _____ wave.
15. The spreading out of a wave as it passes through a narrow opening.
17. An exclusive property if transverse waves only.
18. Occurs when two similar waves traveling in the same direction cross each other.

1. The wave that moves off from the surface after the wave strikes it.
3. The change in speed and direction of waves as it passes from one medium to another.
4. Occurs when wavelength is longer than the with of the opening.
6. The interference that forms a wave that is twice the amplitude of the two traveling waves.
7. The product of transverse vibration in only one plane.
9. Used in sunglasses to reduce the intensity of incident light and eliminates reflected light glare.
16. Occurs when a traveling wave strikes a surface and bounces back.
