Summary
| Description |
English: This is a diagram of the emission spectrum of helium, over the wavelength range of 200 to 1000 nm (near-ultraviolet through near-infrared). Data source: NIST. The upper plot has linearly scaled intensities, while the lower plot has logarithmically scaled intensities (to show fainter lines).
