What can we conclude from the statement that the action and absorption spectrum of photosynthesis overlap? At which wavelengths do they show peaks?

(N/A) $1$. The overlap between the action spectrum and the absorption spectrum of chlorophyll $a$ indicates that chlorophyll $a$ is the primary pigment responsible for photosynthesis.
$2$. The absorption spectrum shows the light wavelengths absorbed by pigments like chlorophyll $a$,chlorophyll $b$,and carotenoids. The action spectrum shows the rate of photosynthesis at different wavelengths.
$3$. Both spectra show peaks in the blue and red regions of the visible light spectrum.
$4$. Specifically,they show peaks in the blue region (approximately $430-470 \ nm$) and the red region (approximately $660-680 \ nm$).
$5$. This confirms that light energy absorbed by chlorophyll $a$ in these specific wavelengths is most effective in driving the photosynthetic process.
