Question

The carotenoids absorb light in the visible spectrum between _____ and _____ wavelengths.

Options
  • A

    400-600 nm

  • B

    530-700 m

  • C

    620-700 nm

  • D

    500-600 nm

Explanation

Carotenoids are a group of pigments that absorb light in the visible spectrum, specifically in the range of 430-470 nanometers (nm). This range corresponds to the orange to red region of the visible spectrum.

This range corresponds to the blue to yellow region of the visible spectrum, which is not the primary absorption range of carotenoids.

The unit "m" stands for meters, which is not the correct unit for measuring wavelengths. The correct unit is nanometers (nm).

Carotenoids are a group of pigments that absorb light in the visible spectrum, specifically in the range of 430-470 nanometers (nm). This range corresponds to the orange to red region of the visible spectrum.

This range corresponds to the green to yellow region of the visible spectrum, which is not the primary absorption range of carotenoids.
