Frequently asked questions
What formula does the EM Spectrum Identifier use?+
It uses λ → band, f, photon energy. The steps section shows the formula with your actual numbers substituted, so you can follow (and verify) every stage of the calculation rather than trusting a black box.
What should I keep in mind when using this calculator?+
One continuous spectrum, one physics — only wavelength changes. The crucial boundary is ~10 eV (124 nm): above it photons can ionise atoms and damage DNA (UV-C, X-, gamma); below it, no intensity of radio or microwave can — it just warms things.
Is the EM Spectrum Identifier free to use?+
Completely free, with no sign-up or limits. All computation happens client-side in your browser, so it is fast, private, and works even on slow connections once the page has loaded.
Can I use this for homework, teaching or exam prep?+
That is exactly what it is built for. The step-by-step working mirrors how solutions are presented in class, so you can check homework, build worked examples for teaching, or practise method recall before exams.
