Light is both a particle and a wave Light has properties of both a particle and an electromagnetic wave but not all the properties of either It consists of photons that travel in a wave like pattern.
Light isn’t made of matter, so it doesn’t have mass It is just a form of energy (also called electromagnetic energy) that travels at a constant speed from one place to another and reflects from the objects When it hits our eye, we see the objects from which the light is reflected or emitted.
