Flashcards
Week 19 - PHY: EM spectrum
Cards in this deck (9)
- 1Define spectrumA range of somrething
- 2Define vaccumA space devoided of matter
- 3Define the EM spectrumAn electromagnetic spectrum is a range of radiation waves that vary in frequency and wavelength (a range of radiation)
- 4State 4 properties of the EM waves- They all transfer energy
- They are all transverse
- They all travel at the speed of light in a vaccum (300,000,000m/s)
- They can be reflected or refracted - 5What are the 7 regions on the EM spectrum?- Radio waves
- Micro waves
- Infrared
- Visible light
- Ultra-violet
-X-ray
-Gamma rays - 6Explain the black colourThis is when all the light waves have been obsorbed and non have been refelected (absence of light)
- 7Explain the white colourWe are able to witness white light when all the different colours are combined
- 8Define dispersionThe separation of a wave into its different colours (fequencies) as it travels through a medium
- 9What are the 3 orders that the EM spectrum is structured in?
