You bring up an interesting point about the relationship between light, matter, and energy. Let's break it down:
Matter: Matter refers to particles that have mass and occupy space. Examples of matter include atoms, molecules, and larger objects composed of these particles.
Energy: Energy is a fundamental concept in physics and is not limited to matter. Energy can exist in various forms, including kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), electromagnetic energy (light), and many others.
Light: Light is a form of electromagnetic energy. It consists of particles called photons, which are massless and travel at the speed of light. Unlike matter, which is composed of particles with mass, light does not have mass and does not occupy space.
While both matter and light are manifestations of energy, they differ in their fundamental properties. Matter is composed of particles with mass, while light consists of massless particles (photons) that carry energy but do not have mass. This distinction allows us to differentiate between matter and light, even though both are forms of energy.
In summary, energy exists in various forms, including matter and light. Matter is made up of particles with mass, whereas light is a form of energy that does not possess mass but is composed of massless particles called photons.
