Photon Energy Calculator (E = hf)
Converts between a photon's wavelength, frequency and energy (in joules and electronvolts) and names the part of the spectrum it belongs to.

Notes
- E = hf = hc/λ: shorter wavelengths carry more energy per photon, which is why UV burns and radio waves do not.
- Visible light runs from about 380 nm (violet) to 750 nm (red), roughly 1.6 to 3.3 eV per photon.
