You’re best bet will be to google something like “wavelengths for peak photosynthesis” there’s lots of articles and pictures that will help explain way better than what I’m capable of.
It’s also important to know that from any graph that’s provided, is relative intensities from one wavelength to another. So there’s no real top of the chart. Or if it makes more sense, a 10 watt light can hit the same peaks as a 1000 watt light. The 1000 watt light will just have a lot more photons in each of the wavelength provided.
