Multiple Choice

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?

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

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

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

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