Question 6 Chlorophyll, the green pigment found in plants, absorbs visible radiation best in the red region and in the blue-violent region. What is the energy of the photons absorbed by plants in the red region at 675 nm? When submitting answers in scientific notation, please use E to represent "x10". An example would be 4.1 x 10<sup>-2</sup>, this would be counted correct as 4.1E-2.
