Question

What are the characteristics of red light, which is absorbed by chlorophylls?

Answer 1

Step-by-step explanation:

The characteristics of red light suitable for photosynthesis are as follows :

a) It has the longest wavelength

b) It has the least energy but sufficient enough to excite the photons. Energy levels other than red light do not raise an orbital electron to an excited, or quantum, state

c) The adsorption rate by the chlorophyll is high

d) It has high electrical efficiency which allows the excitation of photons and release of electrons.

Answer 2

There are choices for this question namely:

A. Its photons have the shortest wavelength in the visual spectrum
B. Its photons have the highest energy in the visual spectrum
C. Its photons have the longest wavelength in the visual spectrum
D. It is not considered a part of the visual spectrum

The correct answer is that its photons have the longest wavelength in the visual spectrum. Chlorophyll, being green in color (around 495 to 590 nm wavelength), reflects this wavelength; not absorbed. Mostly, the chlorophyll absorbs longer wavelengths of light such as red (around 680 nm wavelength) and blue to violet (around 400 to 480 nm wavelnegth).
