Why do you think green plants are green? What wavelength of light is being reflected or transmitted?

Answers

The reason green plants are the color green is that it contains a pigment called chlorophyll and that absorbs the light red long wavelength and blue short wavelength. Green light dose not get absurd it’s reflected and that’s why green plants are green.

Final answer:

Green plants are green because of the pigment chlorophyll, which absorbs most wavelengths of light except for green. The wavelength of light being reflected or transmitted by green plants is in the range of approximately 500-570 nanometers.

Explanation:

Green plants appear green because they contain a pigment called chlorophyll, which absorbs most wavelengths of light except for green. This means that green light is reflected or transmitted by the plant, which is then detected by our eyes as the color green.

The wavelength of light that is being reflected or transmitted by green plants is in the range of approximately 500-570 nanometers. This is within the visible light spectrum, which ranges from about 400 to 700 nanometers.
