What is light and what does it consist of?

Wave-Particle Duality of Light. Quantum theory tells us that both light and matter consists of tiny particles which have wavelike properties associated with them. Light is composed of particles called photons, and matter is composed of particles called electrons, protons, neutrons.

Also, what makes up light?

Light is made up of little packets of energy called photons. Most of these photons are produced when the atoms in an object heat up. Heat “excites” the electrons inside the atoms and they gain extra energy. This extra energy is then released as a photon.

What is light and how is it produced?

Incandescent lights work by putting electricity through filaments, which get hot and light up. Fluorescent lights work by passing electric current through vapor, which produces radiation in the form of light. LED lights use electrons to produce light, and are the most widely available, efficient type of lightbulb.

Is light made up of matter?

Light is a form of energy, not matter. Matter is made up of atoms. Light is actually electromagnetic radiation. Moving electric charge or moving electrons (electric current) cause a magnetic field, and a changing magnetic field creates an electric current or electric field.
