Greenhouse Effect
Cards in this deck (13)
- 1EM Waves- Bundles of energy that travel
- Light is a wave
- A wavelength is the distance between 2 peaks
- As the size of a wavelength decreases, the frequency increases - 2What is Electromagnetic Spectrum- The range of waves (wavelength & frequencies) that light is propagated
- visible light is the light we can see - 3properties of light1. light is a form of energy
2. light travels in straight lines
3. light travels at a speed of 5.0x10>8 m/s --> 300000 km/s !!
4. light can bounce off surfaces
5. light can bend as it passes from one medium to another
6. light is invisible until it reflects off something - 4Sources of lightLuminous
Non-luminous
Shadows - 5LuminousAn object that produces its own light
- 6non-luminousAn object that reflects light
- 7ShadowsPlaces where light is blocked
- 8Incandescencelight emitted from a material. because of its high temperature
- 9Luminescencelight that is generated without heating the object
- 10FlourescenceLight that is emitted during exposure to. ultraviolet light
- 11phosphorescencelight that is emitted due to exposure to ultra violet light and that continues to be emitted for some time in the absence of the ultraviolet light
- 12Chemiluminescencelight that is produced by a chemical reaction without a rise in temperature
- 13Bioluminescencelight produced by living organisms. Chemical reaction within organisms.
