Answer

The photon is a type of elementary particle.

----------------------------------------------------
THE BASIC PROPERTIES OF PHOTONS ARE-
----------------------------------------------------

¤They have zero mass and rest energy.
¤They are elementary particles despite lacking rest mass.
¤They have no electric charge.
¤They are stable.
¤They are spin-1 particles which makes them bosons.
¤They carry energy and momentum which are dependent on the frequency.

That's it
Hope it helps!!!

Answer

Photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum (a completely empty space), have a constant speed of light to all observers. Photons travel at the vacuum speed of light

Answer

Photon:
A photon is a fundamental particle of light and is the smallest unit of light. It is considered both a particle and a wave, according to quantum theory. Photons have no mass, electric charge, or resting mass. They travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second.

Properties of Photons:
- Massless: Photons have zero rest mass, which means they do not have any intrinsic mass.
- Energy: The energy of a photon is directly proportional to its frequency. The higher the frequency, the higher the energy.
- Speed: Photons travel at the speed of light in a vacuum, and nothing with mass can travel faster than them.
- Electrically Neutral: Photons do not carry any electric charge, making them electrically neutral.
- Quantized: Photons exhibit quantized behavior, meaning their energy levels are discrete and not continuous.
- Wave-Particle Duality: Photons exhibit both wave-like and particle-like properties, behaving as waves in some situations and particles in others.
- Polarization: Photons can be polarized, which means their electric and magnetic fields oscillate in specific orientations.

Interaction with Matter:
Photons can interact with matter in several ways, such as absorption, reflection, and transmission. When a photon interacts with an atom, it can be absorbed, causing an electron to move to a higher energy level. The absorbed energy can then be re-emitted as a new photon. Reflection occurs when photons bounce off a surface, while transmission happens when photons pass through a material without being absorbed.
In conclusion, photons are fascinating particles with unique properties that play a crucial role in the behavior of light and electromagnetic radiation. Their wave-particle duality and interaction with matter make them essential in understanding various phenomena in physics.
