Darla noticed that the leaves of a tree in her yard appear green during the day when the sun is shining but look black in the late evening just before dark. Why do the leaves look different at different times of day?
During the day, leaves change all the light to green wavelengths during photosynthesis. At night, there is not enough light for photosynthesis to occur.
During the day, the leaves absorb all the light, except green wavelengths, which are reflected. At night, there is not enough light reflected for eyes to detect.
During the day, the leaves reflect all the light, except green wavelengths, which are absorbed. At night, there is not enough light reflected for eyes to detect.
During the day, green wavelengths are refracted by the leaves and other wavelengths are transmitted. At night, all wavelengths are transmitted which results in a darker color.
