## Who first proposed the idea of quanta?

Niels Bohr and Max Planck, two of the founding fathers of Quantum Theory, each received a Nobel Prize in Physics for their work on quanta.

## What is the mass of photon?

Photons are traditionally said to be massless. This is a figure of speech that physicists use to describe something about how a photon’s particle-like properties are described by the language of special relativity.

Do photons vibrate?

A photon simply does not ‘vibrate’. From a particle perspective, a photon is a mass-less particle with a momentum and two possible states of helicity, which correspond to two different polarizations. Its energy equals the absolute value of the momentum. It has nothing to do with any kind of ‘vibration’.

### What is inside a photon?

In physics, a photon is a bundle of electromagnetic energy. It is the basic unit that makes up all light. The photon is sometimes referred to as a “quantum” of electromagnetic energy. Photons are not thought to be made up of smaller particles. They are a basic unit of nature called an elementary particle.

### How photons are created?

A photon is produced whenever an electron in a higher-than-normal orbit falls back to its normal orbit. During the fall from high energy to normal energy, the electron emits a photon — a packet of energy — with very specific characteristics.

Is photon a particle or wave?

When we’re thinking of light as being made of of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy. Meanwhile, when we think about light propagating as waves, these are waves of electromagnetic radiation.

#### Is a photon a wave or particle?

Light Is Also a Particle! Now that the dual nature of light as “both a particle and a wave” has been proved, its essential theory was further evolved from electromagnetics into quantum mechanics. Einstein believed light is a particle (photon) and the flow of photons is a wave.
