Electromagnetic radiation's states[edit | edit source]

Electromagnetic Light Radiation[edit | edit source]

Electromagnetic Electricity Radiation[edit | edit source]

Photon (Electromagnetic wave radiation) exists in 2 states at specific frequency . .

Heissenberg's uncertainty principle[edit | edit source]

States that

Photon cannot exist in 2 states at the same time

The chance to find one of its state (successful rate of finding photon) is 1/2 where h = p λ . h and p do not change, only wavelength changes with frequency

Mathematically, Uncertainty principle can be expressed as
