The separation of colors by refraction is called:

Which of the following colors is never found in the interior of a rainbow?

It is the interaction of white sunlight with our atmosphere that creates the numerous optical phenomena that take place in the sky.

Superior mirages appear ________ the observed object,and inferior mirages appear ________.

These vertical shafts of light are created by slowly falling crystals of ice.

The secondary rainbow is located outside the primary bow.

Before sunlight interacts with the atmosphere,it is this color.

Refraction of light bends it towards the perpendicular of the slower medium.

When a rainbow is seen in the morning,the Sun is located to the west of the observer and the raindrops are located in the east.

Red light travels the ________ and is therefore bent the ________.

The bending of light by reflection is responsible for such common optical illusions as the apparent displacement of the position of the stars,the Moon,and the Sun.

Refraction is not a part of the optical process of forming halos.

If you see large towers or mountains that seem to appear out of thin air,you are probably witnessing:
