Which of the following statements is true concerning how light interacts with the pigments in a red tomato?
An object is appearing in blue color
means that it is reflecting blue wavelengths while the
complementary wavelengths are absorbed by the object.
In the given case,
The ripening of tomato characterized by the breakdown of
chlorophyll which produces carotenoids i.e. lycopene.
It appears in red color as the pigments absorb blue light.
