Answer the following questions based on the reading passage. Don´t forget to go back to the passage whenever necessary to find or confirm your answers.

1.- How does light travel?

Light from the sun or light bulb moves in straight waves.

2.- Why can we see objects?

Because the light waves hit an object, they bounce off of it. This action is called reflection.

3.- How do light waves act when they hit a smooth or shiny surface?

This odd movement allows you to see yourself. It creates a reflection.

4.- will a lake filled with people boating and swimming act like a mirror? Why, or why not?

Yes. Because the water and glass have a special ability. They can refract, or bend, light.

5.-  What ability of glass allows us to magnify, or make things larger?

The ability of glass to refract light has given us some useful products. Eyeglasses help us see clearly. Magnifying glasses enlarge our view of an object.
