The universe is made up of matter and energy. Matter â anything that has mass and takes up space â is pretty straightforward and easy to grasp, but energy is a bit more abstract. In physics, energy is the ability to do work, or the ability to move or elicit change in matter.
Light energy is the only visible form of energy . Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. In everyday we use the word âlightâ for at least 10 times a day!! Have you ever think about the energy we get from the light.
