Question

What wavelength is most connected with greenhouse effect. And what wavelength is mostly reflected by green plants

stion 4 C. Wavelengths most connected with Greenhouse effect B. D. 1. 5001000 100 nm)

Answer 1

The wavelength connected with green house effect is 4200nm - 15,000nm

Explanation: Green house effect is the heat retention in the atmosphere of the earth due to green house gases like Carbon dioxide, methane, water vapor and other such gases.

Among which carbon dioxide is the major factor. The absorption wavelenghts of these gases in nm are:

• CO2- 4200 to 15,000nm
• H2O-6000 to 6700nm
• N20- 4500, 8000, 17000 nm

Green plants absorb light of wavelength 400-500 nm(blue light) and 650-750nm (red light) and reflect green light of wavelength 550 nm thus making them appear as green.

Explanation: Green plants have pigments (chlorophyll) whcih absorb different photons of light and reflects other photons of light. Green color is reflected by green plants whereas blue light and red light are absorbed. Accordingly 400-500 nm and 650-750 nm is absorbed while 550 nm is reflected which gives the perception of green color for the chlorophyll containing plants
