Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

I don't get it, but I do have deuteranopia.
You have probably heard that plants are green. They are green because they reflect green light
They reflect green light because they can't absorb all of it
Nope! Plants do absorb green light, but since the sun is green, it would be too intense to do it all at once, so they reflect it back as to not overheat, and to let other parts of the plants to absorb it.
Now, you may be asking me, "What do you mean the sun is green?" The sun isn't yellow, it's white, but blue gets stripped out by Rayleigh scattering. "But then how is it green?" White is green as an even temperature white light has a dominant wavelength in green, but a large bandwidth into blue and red. Same reason we use green materials like silver, aluminum, and soda lime glass.
And the green end of the spectrum is the highest energy end. Our solar panels out perform plants in energy production partly because they can tolerate much, much more of the higher energy frequencies
