Wave model

3. waves that do not require medium to transfer energy
5. distance between two identical consecutive points in a wave pattern
8. the number of oscillations per unit time
9. a measure of the energy content of the wave
12. a region in longitudinal where particles are spread out
13. waves where the displacement of the particles is parallel to the direction of the wave motion
15. the time required for a complete oscillation

1. a form of non-ionizing electromagnetic radiation with wavelengths ranging from about one meter down to one millimeter, or frequencies between 300 MHz and 300 GHz
2. radiation with wavelengths shorter than visible light but longer than X-rays
4. waves where the vibration of the particles is perpendicular to the direction of energy transfer
6. waves that require medium to transfer energy
7. motion back and forth about a central point
10. the highest point in a transverse wave
11. the lowest point in a wave pattern
14. thermal radiation, carrying heat
