4. wave motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's ad pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound
6. the measure of sound frequency expressed in terms of Hertz
8. the quantity of energy the wave conveys per unit time across a surface of unit area
9. the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through the emission of a photon, resulting in the production of light
10. a minute energy packet of electromagnetic radiation
12. the substance that transfers the energy, or light from one substance to another substance or from one place to another, or from one surface to another
14. the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid or solid matter) as it propagates away from the source of the sound
15. wave wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.

1. the number of waves that pass a fixed point in unit time
2. energy that comes from a source and travels through space at the speed of light
3. wave occurs when two waves of the same frequency and amplitude are moving in opposite directions and interfere with each other
5. the ability of a quantum system to be in multiple states at the same time until it is measured
7. the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another
11. any higher-frequency standing wave
13. motion motion repeated in equal intervals of time
