THE SPOON LOOKS BENT BECAUSE......

• 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 refracted because the water absorbs different colors of light

• the light waves are reflected because the water absorbs different colors of light
