When light enters a prism, the prism causes the light to ____________ very slightly or to change directions just a bit longer.

In a real rainbow, ________________ in the air act like very small prisms.

Refraction breaks the ______________________ entering the raindrop into color components, just like in the prism.

A double rainbow has a brighter rainbow called a ___________________ rainbow, and a fainter rainbow called the secondary rainbow.

You have probably noticed that rainbows have something to do with the weather. You have probably thought about the fact that the word rainbow has rain in it, and that is when you see __________________.

You do not see a rainbow every time it rains.

White light is a mixture of all the different colors of light that you can see. Red, orange, yellow, green, blue, indigo, and violet (ROYGBIV) can all be found in ____________ light.

Drops of water and sunlight work together to form rainbows.

The speed of light changes when it passes from one medium to another. This change in speed can cause light to change direction. This phenomenon is known as refraction.

When multicolored (polychromatic) light goes from one medium to another, the different colors change speed

differently. This makes each color change direction differently.

A prism compounds the effect of color dispersion.

When light shines on an object, it is reflected, absorbed, or transmitted through the object, depending on the object’s material and the frequency (color) of the light.

The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path

bends.

A wave model of light is useful for explaining brightness, color, and the frequency dependent bending of light at a surface between media.

Objects absorb some colors of light and scatter others. The combination of the colors that is scattered appears to me as a particular color, which is the color I associate with the object.

The different colored lines absorb different colors of light and scatter others. The combinations of the colors that are scattered by each line appear to me as the particular

colors we associate with the line.

In a real rainbow, raindrops in the air act like very small ____________.

Light enters the raindrops and gets bent by them. Each color of light is bent slightly ________________.

The light entering a _______________ is reflected back at the far side of the raindrop.

Refraction breaks the light entering the raindrop into color components, just like in the ________________.

The refraction of the light by the raindrops causes the colors to spread out to create a semicircle of color in the sky, or a ________________.

When I see a rainbow, I am seeing reflected light.

Transmission means

What is the evidence that an object absorbs light?

Sunglasses

Unpolished wood

Why do you feel hotter in dark color clothing than light color clothing?

A prism is a way to break ___________ light into its color components.
