The flashcards below were created by user tlsmith9 on FreezingBlue Flashcards. What would you like to do?


  1. ______ has(have) wavelengths shorter than visible light.

    a)Radio waves
    b)Microwaves
    c)Infrared radiation
    d)Ultraviolet radiation
    Ultraviolet
  2. Solar radiation peaks in the ________ portion of the electromagnetic spectrum.

    a)microwave
    b)visible
    c)x-ray
    d)infrared
    visible
  3. The blackbody radiation law that predicts the wavelength of most intense radiation is known as the

    a)Stefan-Boltzmann law.
    b)Wien's displacement law.
    c)law of energy conservation.
    d)first law of thermodynamics.
    Wien's displacement law

    All objects emit and absorb all forms of electromagnetic radiation. However, the wavelength of most intense radiation emitted by a blackbody is inversely proportional to the absolute temperature of the object.
  4. The process whereby electromagnetic radiation is converted to heat is known as

    a)absorption.
    b)scattering.
    c)reflection.
    d)transmission.
    absorption

    Absorption is an energy conversion process whereby some of the radiation striking the surface of an object is converted to heat energy.
  5. Stratospheric ozone protects living organisms from exposure to potentially lethal intensities of

    a) x-rays.
    b)ultraviolet radiation.
    c)infrared radiation.
    d)visible light.
    ultraviolet radiation

    Chemical reactions involved in the formation and dissociation of ozone in the stratosphere shields organisms at the Earth's surface from exposure to potentially lethal intensities of solar ultraviolet radiation.
  6. The Antartic ozone hole develops during

    a)summer.
    b)March and April.
    c)the Southern Hemisphere spring.
    d)January and February.
    the Southern Hemisphere spring

    For about six weeks during the Southern Hemisphere spring (mainly in September and October), the ozone layer in the Antartic stratosphere (mostly at altitudes from 11 to 23 km, or 7 to 14 mi) thins drastically and then recovers during November.
  7. A gas that acts as a catalyst in chemical reactions that convert ozone to oxygen is

    a)methane.
    b)carbon dioxide.
    c)chlorine.
    d)water vapor.
    chlorine
