How this service works
Physics conversion tool linking light wavelength, frequency, and photon energy — supply any one of nanometers, hertz, joules, or electron-volts and get the others computed exactly from fundamental constants. For optics, photonics, and physics-education agents.
Output
Returns computed values for all of: wavelength in nanometers, frequency in hertz, photon energy in electron-volts, and energy in joules — derived exactly from whichever input quantity was supplied, using fundamental physical constants (Planck's constant, speed of light).
Example use cases
Example prompt
“What's the photon energy in eV and joules, and the frequency in Hz, for a 532 nm green laser wavelength?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/ev-to-nm-converterWhen to prefer
Use this endpoint when you need exact, physically rigorous conversion between electromagnetic wave properties (wavelength, frequency, photon energy in eV or joules) for optics, photonics, spectroscopy, or physics education tasks. Prefer it over general-purpose calculators when you specifically need all four quantities computed simultaneously from a single input.
Side effects
- Missing or null input — no wavelength_nm or frequency_hz provided, returns error
- Non-numeric string values for wavelength or frequency fields cause parsing errors
- Physically impossible values (e.g. negative wavelength, zero frequency) may return error or undefined behavior
- Network timeout if service is temporarily unavailable
