Across
- 4. Wave Speed: The product of a wave’s frequency and wavelength.
- 5. The restriction of a wave so that it can only oscillate in a single plane. This can only occur for transverse waves.
- 7. __________ Waves: A wave with oscillations that are perpendicular to the direction of energy propagation. Electromagnetic waves are examples of transverse waves.
- 9. The number of complete oscillations of a wave (wave cycles) per second. It is the inverse of the time period.
- 10. _______________ Spectrum:The spectrum of _______________ waves, consisting of Gamma Rays, X-Rays, Ultraviolet, Visible Light, Infrared, Microwaves and Radiowaves.
- 11. _____________ Wave: A wave with oscillations that are parallel to the direction of energy propagation. Sound waves are an example of a longitudinal wave.
- 12. _____ Difference:The difference in phase between two points on a wave. It is usually expressed in radians.
Down
- 1. ___________ Waves: A wave that transfers energy from one point to another, without the transfer of matter.
- 2. A wave’s maximum displacement from its equilibrium position. Displacement:The distance and direction that a vibrating particle or wave has travelled from its equilibrium position.
- 3. The power transferred per unit area. It is proportional to the square of a wave’s amplitude.
- 6. The distance between two identical positions on two adjacent waves. It is commonly measured from peak to peak or trough to trough.
- 8. The time it takes for one complete wave to pass a given point. It is the inverse of frequency.
