Across
- 1. -The spreading of waves passing through an opening or around a barrier
- 3. -The shortest repetition length for a periodic wave
- 5. -The distance from a mirror to its focal point
- 7. -The combining of two more more waves at a location in space
- 10. -Large increase in the amplitude of a vibration when the force is applied at the natural frequency of the medium or object
- 12. -The bending of light that occurs at the interface between two transparent media. It occurs when the speed of light changes
- 14. -A peak of a wave
Down
- 1. -A change in the frequency of a periodic wave due to motion of the observer, the source, or both
- 2. -A valley of a wave
- 4. -The spreading of light into a spectrum of colors
- 6. -The location at which a mirror focuses rays parallel to the optic axis
- 8. -Position on a standing wave pattern where amplitude is zero
- 9. -The shortest length of time it takes a periodic motion to repeat (1/f)
- 11. -Position on a standing wave pattern where the amplitude is maximum
- 13. -The number of times a periodic motion repeats in a unit of time
