sci.photon-energy-wavelength Calculator
Calculates photon energy E = hf = hc/λ from frequency or wavelength and photon flux from power. Visible photon at 500 nm: E = 3.97 × 10⁻¹⁹ J = 2.48 eV — a 1 W green laser emits 2.5 × 10¹⁸ photons per second.
Inputs
Lambda Nm
Distance between successive wave crests. Related to frequency: λ = speed / frequency.
Power Mw
Rate of energy transfer (W). P = V×I (electrical). P = F×v (mechanical). 1 horsepower ≈ 746 W.
Qe Pct
Useful output divided by total input, as a percentage. 100% is impossible due to losses (heat, friction, resistance).
Results
photon energy E (eV)
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
photon flux (photons/s)
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
photocurrent I (μA)
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
E = hc/λ
Reference formula or conversion factor shown for context.
colour
The colour classification or output colour code computed from the inputs.
