100 cm = 1 m+ Transcribed Image Text: Plants absorb mainly red (650 nm) and
blue (450 nm) wavelengths while
reflecting mostly green. This is how
the chlorophyll molecule responds to
EM-waves, and the reason why plants
appear green most of the time. Shown
below are 3 hypothetical energy levels
of the chlorophyll molecule. A) What
is the difference in energy levels
corresponding to red wavelengths? B)
What is the difference in energy levels
corresponding to blue wavelengths?
C) If an electron “jumped” from energy
level 3 to energy level 1, what
wavelength photon would be emitted,
and D) could our eyes detect this
wavelength (use the spectrum shown
below)? (650 nm = 650 x 10- m = 6.5
x 10-7 m)

D)
Type Y for Yes
(we could detect this wavelength) and
N for No.
