Duckweed is a tiny floating aquatic plant that can reproduce so rapidly that it can completely cover the surface of small fish hatchery ponds. one proposal to limit the growth of this invasive plant is to use colored panels to shield the ponds, inhibit photosynthesis, and kill the pest. what color filters would you order for the panel in this project? what wavelength of light will be absorbed by these filters? do you think this proposal will be effective in killing the duckweed?
