Wavelength to Energy Calculator

Online energy of light with wavelength calculator to calculate energy in Joules, Kilojoules, eV, kcal. Planck's equation is used to describe the energy of light using wavelength (λ). Photon is the tiny fundamental part of the visible light. It is characterised by either λ or energy of light (E). Photon energy refers to the energy of a single photon with a particular amount of wavelength and frequency. Use our wavelength to energy calculator to find the energy of light.

Formula:

Energy of Light = (6.626 × 10-31 × c) / w(m) Where, e = Energy c = Speed Of Light(300000000 m/s) w = Wavelength

Example:

Calculate energy of light having a wavelength of 12 cm.

Solution:

Energy = (6.626 × 10-31 × 300000000 )/ 0.12
= 1.6565e-27 J
