Can you tell from these absorption spectra whether red light is effective in driving photosynthesis?

Plants assimilate blue/green light and reflect yellow and red wavelengths of light. These assimilation spectra tells us that green and yellow wavelengths of light are much more effective than red light.

Explanation:

To provide plants the best possibility to perform photosynthesis, a blue light within the range of 425–450 nanometers  is much better than red which is absorbed by chlorophylls, used effectively and it is generally less energetic than blue.

Some part of absorbed blue light is not going to photosynthesis as carotenoids do not conduct assimilated energy efficiently to chlorophyll. Plants embodying mostly cartenoids show red, orange or yellow. Red light matches with the absorption peak of chlorophylls, which do photosynthesis to produce sugars and carbons the plant cells´ structure blocks.

the earthquake in haiti was a magnitude of 7.0 according to the u.s geological survey yet the smaller earthquake in haiti killed more than 200,000 and left more than 1.2 million people homeless. the chile earthquake was a magnitude of 8.8 and 500 times more stronger but chile's earthquake only injured 712 people.
