1. Electromagnetic radiation is a broad range of energetic emissions.
2. Spectrum is a good description of the types of energy found in electromagnetic radiation because spectrum means any of variation of color or object.
3. Visible light is useful in plant photosynthesis, while other forms of electromagnetic radiation are not.
4. a. infrared, ultra-violet, visible
b. infrared radiation: Causes certain bonded atoms to vibrate more energetically.
ultraviolet radiation: Potentially can cause a sunburn, and witch ling-term exposure is linked to skin cancer.
visible radiation: Energizes electrons in some chemical bonds.
5. Ultraviolet light is often used to sterilize chemistry laboratory goggles because it can kill bacteria and destroy viruses.
6. Infrared radiation is absorbed by CO2 H2O molecules in the atmosphere.Visible Radiation is scattered by water, air, and dust. Ultraviolet radiation is absorbed in the stratospheric ozone layer.
7. Solar radiation determines climates and weather, and also powers the hydrologic cycle.
8. Lake water reflects more solar radiation than asphalt because it is a lighter in the color spectrum. Asphalt barely reflects any light.
