What is the Spectroscopy Calculator?

The Spectroscopy Calculator computes the relationship between frequency, wavelength, and energy of electromagnetic radiation using the fundamental formulas of spectroscopy. By entering any one known value—frequency (ν), wavelength (λ), or energy (E)—the calculator automatically determines the other two values using the speed of light and Planck’s constant. This tool helps students, educators, and scientists quickly convert between spectroscopic quantities, analyze light properties, and better understand the behavior of photons in various experiments.

How to Use:

1. Enter Frequency (ν) [Hz]: Input the known frequency in hertz if available.
2. Enter Wavelength (λ) [m]: Input the known wavelength in meters if available.
3. Enter Energy (E) [J]: Input the known energy in joules if available.
4. Click “Calculate”: The results for all three parameters are displayed, including frequency, wavelength, and energy.
5. Review the Result: Use the calculated values to analyze spectroscopic data, plan experiments, or verify theoretical calculations.
