How this service works

Converts electromagnetic wavelength in nanometers to photon energy in joules and electron-volts, and back, using exact physical constants for the speed of light and Planck's constant. For spectroscopy analysis, optics design, and astronomy agents working with light-frequency data.

Output

Returns the photon energy corresponding to the given wavelength or frequency, expressed in both joules and electron-volts, computed using exact values of Planck's constant and the speed of light.

Example use cases

Example prompt

“What's the photon energy in joules and electron-volts for a 532 nm green laser wavelength?”

When to prefer

Choose this endpoint when an agent needs a precise, physics-constant-based conversion between electromagnetic wavelength or frequency and photon energy in SI units (joules) and electron-volts, particularly for spectroscopy analysis, laser optics design, or astronomy workflows dealing with light-frequency data. Prefer over a general math API because this uses exact physical constants and returns both joule and eV representations in one call.

Side effects

Missing both wavelength_nm and frequency_hz — endpoint requires at least one input
Invalid non-numeric string for wavelength or frequency — returns parse error
Wavelength of zero or negative value — physically undefined, likely returns error
Extremely large or small values outside practical physical range may produce unexpected results
Payment failure via x402 protocol — call rejected before computation
