Question

Start with the Gizmo and select the "Color" Tab.
The first variable we are testing is the light wavelength.
Leave the temperature at 30 degrees.
Leave the light intensity at 30%
Leave the CO2 levels at 500 ppm
Start testing the light wavelength by moving the bar all the way to the left, and then move the bar over 50nm at a time. Start at 400 nm
Your starting point should look like this image below:
Moving the Light Wavelength 50nm at a time, which Wavelength produced the most Oxygen (O2)? Choose the best option.
450 nm
500 nm
600 nm
650 nm

Answer 1

650 nm

Red light (around 650–660 nm) is most effective for photosynthesis in this setup, so it produces the most O2.
