Across
- 4. a type of heat transfer that occurs within a liquid or gas
- 5. the speed of an object, normally measured in m/s
- 6. change in velocity
- 7. a type of heat transfer that occurs with infrared light
- 8. a material that resists the transfer of heat or electricity
- 9. the number of cycles of wave per unit of time, normally measured in Hz. E.g. 2cycles/1s = 2Hz, 4cycles/2seconds=2cycles/1second=2Hz
- 10. light amplification by stimulated emission of radiation
- 11. the property of a material to reflect a wave back out
Down
- 1. the strength of a wave
- 2. the spectrum of electromagnetic energy that ranges from Gamma Rays to Microwave and Radio Waves
