## Wavelength to Energy Calculator

Enter the values of  Planck’s Constant h(6.626176*10-34 J-sec), Speed of Light c(299792458 m/s) &  Wavelength λ(m) to determine the value of Wavelength to Energy E(J).

 Enter Wavelength: m Result – Wavelength to Energy: J

## Wavelength to Energy Formula

The Wavelength to Energy E(J) in Joules is Equal to the Planck’s Constant h(6.626176*10-34 J-sec) in 6.626176*10-34 Joules-second and Multiply the Speed of Light c(299792458 m/s) in 299792458 meter per second and is Divided by the Wavelength λ(m) in meter.

The Formula of Wavelength to Energy can be written as,

E(J) = h(6.626176*10-34 J-sec) * c(299792458 m/s) / λ(m)

Here,

E(J) = Wavelength to Energy in Joules

h(6.626176*10-34 J-sec) = Planck’s Constant in 6.626176*10-34 Joules-second

c(299792458 m/s) = Speed of Light in 299792458 meter per second

λ(m) = Wavelength in meter

Wavelength to Energy Calculation:

1) Calculate the Wavelength to Energy and given for the Wavelength = 100m.

E = h * c / λ

E = 6.626176*10-34 * 299792458 / 100

E = 1.9864776e-27J.

2) Calculate the Wavelength and given for the Wavelength to Energy = 1.9864776e-27J.
