Centimeter to Wavenumber Calculator

Convert wavelengths in centimeters to wavenumbers in reciprocal centimeters (cm⁻¹). This calculator is useful in spectroscopy and physics for analyzing light and wave properties.

Input Parameters

Calculation Results

Wavenumber (cm⁻¹)

Calculation Formula

Wavenumber (cm⁻¹) = 1 / Wavelength (cm)

Where:
- Wavenumber is the measure of the number of wavelengths per unit distance
- Wavelength is the distance between successive crests of a wave in centimeters
