E = hc / wThe above equation reads, energy (E) equals Planck鈥檚 constant (h) times the speed of light (c) divided by the wavelength (w). This radiation energy is in terms of a single unit of light called a photon.

How do you calculate photon energy from wavelength?
Calculation Theory Photon Energy and Wavelength The energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: E = hc/ l (equation 1)
How to calculate the wavelength of a wave?
To calculate the wavelength, you need to know either the frequency or the energy of the radiation. 590 kHz? E = hc 位 or 位 = hc E, where h is Planck’s constant.
What is the relationship between wavelength and energy of light?
The energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: where h is Planck’s constant (6.6261 x 10 -34 J*s) and c is the speed of light (2.9979 x 10 8 m/s).
What is the wavelength of beam of light?
The beam of light is of wavelength 422.2 nm. The energy possessed by a photon is termed as photon energy, and is inversely proportional to the electromagnetic wave of the photon, by the relation Hence, the photon with a large wavelength possesses a small unit of energy whereas the photon with a smaller wavelength gives a large amount of energy.
