    The Fitzpatrick scale (also Fitzpatrick skin typing test; or Fitzpatrick phototyping scale) is a numerical classification schema for human skin color.

  4. Sunburn - Wikipedia

    en.wikipedia.org/wiki/Sunburn

    Sunburn effect (as measured by the UV Index) is the product of the sunlight spectrum at the Earth's surface (radiation intensity) and the erythemal action spectrum (skin sensitivity). Long-wavelength UV is more prevalent, but each milliwatt at 295 nm produces almost 100 times more sunburn than at 315 nm.

    en.wikipedia.org/wiki/Ultraviolet

    Sunburn effect (as measured by the UV index) is the product of the sunlight spectrum (radiation intensity) and the erythemal action spectrum (skin sensitivity) across the range of UV wavelengths. Sunburn production per milliwatt of radiation intensity is increased by nearly a factor of 100 between the near UVB wavelengths of 315–295 nm.

    There are some common types of spectrophotometers include: UV-vis spectrophotometer: Measures light absorption in UV and visible ranges (200-800 nm). Used for quantification of many inorganic and organic compounds. 1. Infrared spectrophotometer: Measures infrared light absorption, allowing identification of chemical bonds and functional groups. 2.

  9. Sun tanning - Wikipedia

    en.wikipedia.org/wiki/Sun_tanning

    With the production of the melanin, the skin color darkens. The tanning process can be triggered by natural sunlight or by artificial UV radiation, which can be delivered in frequencies of UVA, UVB, or a combination of both. [7] The intensity is commonly measured by the UV Index. [8]
