Across
- 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.
Down
- 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
