After testing refraction of light in water, Victor makes the following conclusion.

Objects look broken when they are in water, so light is reflected in water.

Is Victor's conclusion accurate?

• Yes, because the objects appear broken in water, they are reflected

• Yes, because all objects reflect light

• No, because objects submerged in water do not appear broken

• No, because objects appear broken in water due to refraction of light.
