If there was no atmosphere surrounding the Earth, the sky during the day would appear what color? | black |
When sunlight strikes an object and the light is sent in all directions, the light is said to be | scattered |
The bending of light as it moves through an object is | refraction |
The breaking up of white light by selective refraction is | dispersion |
The type of mirage that makes objects appear higher than they actually are is | superior mirage |
The bending of light as it passes around an object is called | diffraction |
For halos,tangent arcs, and sun pillar to form this must be present | ice crystals |
If you were standing on the moon, the color of the sky would be | black |
Which of the following processes must occur in a raindrop to produce a rainbow? | refraction, reflection, and dispersion of sunlight |
As light passes through ice,___ light is bent the least and is, therefore observed on the __ of halos and sundogs. | red, inside |
On a foggy night it is usually difficult to see the road when the high beam lights are on because of the __ light | scattering |
If you looked in the general direction of the sun you would not be able to see a | rainbow |
If the setting sun appears red you amy conclude that | only the longest waves of visible light are striking yur eye |
Clouds in the tropics tend to move from east to west. Consequently, which rhyme best describes a rainbow seen in the tropics? | rainbow at the brak of dawn/ means, of course, the rain is gone |
When distant mountains appear blue, it is mainly due to the __ of light | scattering |
