Answer:
blue-violet
Explanation:
Generally the appearance of a photosynthetic plants depends on the wave of light on the absorption spectrum that the pigments absorbs. Thus a leaf appears green at sight because the chlorophyll pigment absorbed wavelength of lights in red-blue-violet region, and reflect green back to the eyes.
Carotenoids appears as orange-yellow in color to eyes.Thus the plant in the question is a carotenoids. They usually absorbed light in blue-violet region of absorption spectrum. Therefore since this plant is a carotenoids, definitely it must absorbed in Blue-violet ,(400-550mn) and appear orange-yellow since it did not absorbed this but reflects back to eyes.
The wavelengths of visible light that are being absorbed by this pigment is: blue and violet.
A chlorophyll can be defined as the pigment of a photosynthetic plant that absorbs and reflects light of specific wavelengths.
Basically, chlorophyll is mainly responsible for the yellow-green color we see on the leaves of a photosynthetic plant.
The particular wave of light on an absorption spectrum that the pigments of a photosynthetic plant absorbs typically affects its appearance to the human eyes.
In this context, some photosynthetic plants (autotrophs) such as carotenoids have a unique photosynthetic pigment, which makes their leaves to appear reddish-yellow to the human eyes.
Also, since the plant is a carotenoid, the wavelengths of visible light that are being absorbed by this pigment is blue and violet.
