This tool calculates the wavelength from the given energy value for you.
How to Use the Wavelength from Energy Calculator
To use this calculator, simply input the energy value in electron volts (eV) into the provided field and click the “Calculate” button. The Planck’s constant and the speed of light are pre-filled with standard constant values for your convenience. The result will display the corresponding wavelength in meters.
Explanation of the Calculation
The relationship between the energy of a photon and its wavelength can be described using the equation:
Wavelength (λ) = (Planck’s Constant (h) * Speed of Light (c)) / Energy (E)
Where:
– Planck’s Constant (h) is approximately 4.135667696×10⁻¹⁵ Js
– Speed of Light (c) is approximately 2.99792458×10⁸ m/s
– Energy (E) is the energy of the photon in electron volts (eV).
Limitations
This calculator assumes the values for Planck’s constant and the speed of light are precise and invariant. It is also limited to scenarios where the energy input is valid and greater than zero. Any deviations in the constants or inappropriate energy values can lead to incorrect results. Always ensure physical constants are precise and inputs are accurate.
