Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How heavy is Photon?Massless
2. What is the fundamental nature?Elementary particle, quantum of the electromagnetic field
3. What is the speed in vacuum?Constant, approximately 299,792 km/s
4. How fast does a photon travel?Photons travel at about 299,792 kilometers per second, the same speed in a vacuum for everyone.
5. Why do photons have no mass?Photons are massless, which lets them move at the constant speed of light and carry electromagnetic force between charged particles.

Quantum Field Theory: A theoretical framework describing fundamental particles and forces as excitations of quantum fields.
Wave-Particle Duality: The quantum mechanical principle that particles can exhibit wave-like and particle-like properties.
Photoelectric Effect: The emission of electrons from a material when light shines on it, explained by Einstein's photon theory.
Boson: A class of elementary particles with integer spin, including photons.
