The particles that make up light are called photons. They are tiny packets of energy that have no mass and travel at the speed of light.
Photons behave both like waves and particles. They can travel through space as a wave, but also interact with matter as discrete particles.
When photons are in motion, they create electromagnetic radiation. This includes all types of light, from radio waves to gamma rays.
The energy of a photon is directly proportional to its frequency. This means that photons with higher frequencies have more energy than those with lower frequencies.
The particle nature of light helps to explain the photoelectric effect, where electrons are emitted from a material when light is shined on it. This is because photons with enough energy can transfer their energy to electrons, causing them to be released from the material.
