Properties of Light

Properties of Light includes reflection and refraction of light, as well as lenses. Although light travels in a straight line, reflection and refraction are able to change the direction of light. Reflection is when a ray of light is hits a medium and is "thrown back" in the direction of its source. Refraction is when the ray of light goes through a denser medium and bends. The study of lenses is just a more specific study of refraction. All these are new to me, as I never imagined that light could change direction. It is a really interesting topic and was a real eye-opener to me
