ATMS 120 Midterm 2 Test
With Solution
Colors in the atmosphere - ANSWER -all the colors we see are not in the
rainbow
-you see color on objects because all the rest of the colors are absorbed and
the color you see is being reflected by the object
Light and color perception by the human eye - ANSWER -rods: respond to all
wavelengths of visible light, allows us to see light and dark
-cones: respond to different wavelengths, some red, blue, green, etc
Color - ANSWER white vs black: white= all colors are perceived by the eye at
the same intensity
-color: visible light of a different frequency that strikes the eye
Blue Skies - ANSWER visible light is scattered by air molecules- the efficiency
of scattering is wavelength dependent- blue light is 10 times more efficient
scattered than red light
, Rainbow - ANSWER -when light passes through the air to the water it is
refracted or bent
-the amount of refraction is dependent if the color of light
-red light is bent less than the violet light
-dispersion: light of a different wavelength is bent differently as it passes
through a medium
-the ingredients of a rainbow= rain and sunshine, postion= face the rain with
the sun to your back, bows 42 degrees with light
hurricanes (tropical cyclones) spin - ANSWER they spin because the earth
spins beneath them
typhoons are where - ANSWER japan and Asia area
cyclones are where - ANSWER africa india and australia area
___ percent of hurricanes are in the Northern Hemisphere - ANSWER 66
why don't hurricanes cross the equator - ANSWER ciriolous effect, depend on
the way the earth spins
