# how to calculate energy using wavelength 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.
