- 4. Angle of incidence and angle of reflection are ____.
- 7. The wave that moves off from the surface after the wave strikes it.
- 8. The interference that leads to the canceling out of the waves to give zero Resultant.

Down
- 1. The spreading out of a wave as it passes through a narrow opening.
