Many types of light come from the Sun, ranging from infrared to ultraviolet. There is a small range of wavelengths of light that humans can see within the larger spectrum of light. What do we call the range of the spectrum that humans can see?

• visible light spectrum

• perceived spectrum

• high intensity spectrum

• color wheel spectrum

Sam was sitting at his desk in front of a window doing his homework. Sunlight shined through the window and a glass of water on the desk and created a rainbow across Sam's paper. Where did the colors in the rainbow come from?

• There was a chemical reaction between the sunlight and water that created the colors

• Since the glass was curved, it made the sunlight change colors.

• The white sunlight was separated into all the colors that make up white light.

• The only way the rainbow could appear is because of a picture on the glass

Jessica knows that a rainbow is made up of the following colors of light: red, orange, yellow, green, blue, indigo, and violet. She has seven flashlights that each has a bulb matching a color of the rainbow, and she wants to try and make white light. Which of her seven colors would she have to mix to get white light?

• Just the bright colors: red, orange, and yellow

• All of the colors she has: red, orange, yellow, green, blue, indigo, and violet

• Every other color: red, yellow, blue, and violet

• uShe can't do it: Mixing the colors will make the light darker, not white.

Within the visible spectrum of light, there are many colors: red, orange, yellow, green, blue, indigo, and violet. What characteristic of each of these colors makes this spectrum of light visible to the human eye?

• Each color has a different wavelength

• Each color travels at a different speed.

• Each color must travel a different distance to our eyes.

• Each color has a different level of intensity.

Sound waves need to travel through something made of atoms or molecules in order to keep moving. They travel at different speeds through different materials. Through which of the following would they be likely to travel fastest?

• air

• water

• juice

• wood

Jacob went down to the lake on a very still day. The water's surface was completely smooth and he could see a tree reflected perfectly in the water. A breeze came up and disturbed the surface of the water and the reflection of the tree disappeared. Why could he see the tree's reflection when the water was still, but not when it was disturbed?

• The disturbed surface made the light waves reflect in many directions, breaking up the image.

• The disturbed surface allowed some of the light waves to penetrate into the water, making gaps in the image.

• The disturbed surface kept the light waves from reflecting, making it impossible to see an image.

• The disturbed surface changed the light waves' wavelengths, changing the reflected image
