Quantum
A packet of light energy is called a photon.
Photon.
The smallest particle or packet of light energy you can get.
Not exactly, they are minute energy packet of electromagnetic radiation.
Photons
Its a packet of energy.
A packet of photons.
Either as: A particle, the photon, A packet of energy, the quantum of electromagnetism(still known as the photon), and A wave of a specific frequency, a wave of radiation that has a certain energy
A tiny particle or packet of light is called a photon. These particles are the basic unit of light and carry electromagnetic radiation.
Photon
These packets of energy are called photons, which are exactly that - little packets of energy! Sometimes they behave as particles, and other times they tend to act like waves. Visible light often comes from atoms that are excited to a higher energy state, then drop back down.
A particle of light. Or, in general, of an electromagnetic wave.
