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

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

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

• She cannot do it: Mixing the colors will make the light darker, not white.

Ultraviolet light comes from the Sun and can sometimes cause serious health issues such as skin cancer. Why does ultraviolet light have this effect on our bodies, but visible light does not?

• Ultraviolet light has more energy than visible light.

• Ultraviolet light move faster than visible light.

• Ultraviolet light has less energy than visible light.

• Ultraviolet light is attracted to our skin
