1. Electromagnetic radiation consists of a broad range of energetic emissions. Particular types of electromagnetic radiation, represents a particular energy level that make up the electromagnetic spectrum.
2. Spectrum is a good descriptor of the types of energy found in electromagnetic radiation because spectrum means" any of various continua that resemble a color spectrum in consisting of an ordered arrangement by a particular characteristic (as frequency or energy)" Merriam Webster.
3. Visible light is useful in plant photosynthesis, while other forms of electromagnetic radiation are not because visible radiation can energize electrons in some chemical bonds. Visible light interacts with electrons in chlorophyll molecules, which provide the energy needed for photosynthesis reactions.
4. a. Types of electromagnetic radiation: infrared, ultra-violet, visible
b. infrared radiation: causes certain bonded atoms to vibrate more energetically.
ultraviolet radiation: can cause a sunburn, and witch ling-term exposure is linked to skin cancer.
visible radiation: can energize electrons in some chemical bonds.
5. Ultraviolet light is often used to sterilize chemistry laboratory goggles because it can kill bacteria and destroy viruses, while visible light can energize electrons in some chemical bonds.
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 powers the hydrologic cycle.
8. Lake water reflects more solar radiation than asphalt because it is a lighter color, and the asphalt reflects almost not solar radiation.
