# Fundamental Physics/Quantum

## Quantum

A massless quantity of a constant value known as Plank's constant

Notation

${\displaystyle h}$

Value of h

${\displaystyle h=constant}$

Mathematical formula

${\displaystyle h=p\lambda ={\frac {E}{C}}\lambda }$

## Quantum energy or Photon

Represents the energy of electromagnetic heat

${\displaystyle E=hf=h{\frac {C}{\lambda }}}$

From above,

${\displaystyle E\lambda =hC}$

Heat energy wave of a massless quantity known as quantum travels at a fast speed equals to speed of visible light

## Characteristic

### Wave-Particle duality

Quanta processes Wave-Particle duality . Quanta exists as wave or particle

Some time Quanta behaves as a particle

${\displaystyle p={\frac {h}{\lambda }}}$

Some other time Quanta behaves as a wave

${\displaystyle \lambda ={\frac {h}{p}}={\frac {C}{f}}}$

### Photon's state

Photon represents quantum's energy

${\displaystyle E=hf}$

Which can be found in 2 states Radiant photon and no-radiant photon . Radiant photon generates light just like visible light . Non-radiant photon generates electricity

• Radiant photon . ${\displaystyle E=hf_{o}.f_{o}={\frac {C}{\lambda _{o}}}}$
• Non - radiant photon . ${\displaystyle E=hf.f_{o}={\frac {C}{\lambda }}}$
