The picture below shows a spoon in a glass of water. Why does the spoon appear bent?

• the light waves are refracted as they change speed when they pass from the water to the air

• the light waves are reflected as they change speed when they pass from the water to the air

• the light waves are absorbed when they pass from the water to the air

• the light waves bounce off of the water
