Wavenumber to wavelength converter

Wavenumber (\( k \)) is defined as the number of waves per unit distance and is typically given in cm⁻¹. The relationship between wavenumber and wavelength (\( \lambda \)) is given by: \[ \lambda = \frac{1}{k} \] where \( \lambda \) is in centimeters. To convert \( \lambda \) to nanometers (nm), we multiply by \( 10^7 \): \[ \lambda_{\text{nm}} = \frac{10^7}{k} \] Therefore, if you input a wavenumber in cm⁻¹, the corresponding wavelength in nm can be calculated using \( \lambda_{\text{nm}} = \frac{10^7}{k} \).
