Which of these is most important for splitting the Sun's light into its separate colors?

Halos:

Clouds that refract sunlight or moonlight and take on bright violet,green,and pink colors are called:

Why don't halos display the colors of a rainbow?

The ________ is seen most often in morning and late afternoon when the Sun is near the horizon.

The angle of incidence is equal to the angle of ________.

________ occurs when light that is traveling through a transparent material reaches the opposite surface and is reflected back into the transparent material.

Because the glory forms opposite the Sun's position,the observer's shadow will always be found within the glory.

Which of these are the primary optical phenomena causing a rainbow?

A layer of very warm,low density air near the surface causes light to:

If you want to see the glory from the surface of the Earth,which conditions must be met?

If you see a rainbow in the afternoon,it means the bad weather has already passed.

In order to see a rainbow,an observer must ________ the Sun and ________ the rain.

You will not be able to see a rainbow if the Sun is greater than ________° above the horizon.

A ________ is one of the few optical phenomena more frequently observed with the moon than the sun.

We are able to perceive light as bending.

Why are mirages generally associated with either very hot surface temperatures or very cold surface temperatures?

________ occurs when cold air near the surface bends light in the same direction as the Earth's curvature,causing the object to appear suspended above the horizon.

The ________ is not often seen by earthbound observers.
