Spectral / Energy Unit Converter calculator
Enter a wavelength to see frequency, wavenumber, photon energy and equivalent kT temperature.
Category: Unit Converters
Formula: E = hν = hc/λ = hc·ν̃
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Wavelength | lam | nm | 532 |
Result with the default inputs
- λ: 532 nm
- λ: 0.532 µm
- ν: 563.5197 THz
- ν̃: 18796.9925 cm⁻¹
