Concept introduction:
Energy is proportional to the frequency and is expressed by the Plank-Einstein equation as follows:
Here,
The equation that relates to the frequency and wavelength of electromagnetic radiation is as follows:
Here,
Equation (1) can be modified as follows:
(b)
Interpretation:
The energy of a photon of visible light with wavelength
Concept introduction:
Electromagnetic waves are radiations that are formed by oscillating electric and magnetic fields. The electric and magnetic field components of an electromagnetic wave are perpendicular to each other.
Energy is proportional to the frequency and is expressed by the Plank-Einstein equation as follows:
Here,
