WebLight travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.) Nothing travels faster than light energy. WebThe light will take the path from outside to your eye that spends the least time You can also see that the rule from earlier still applies: when the light enters the glass the ray is bent towards the normal. When it leaves the glass, it is bent away from the normal, and regains the same angle as before it entered the glass. Consider the following
