Question

More than 50% of incident solar radiation is PAR.

  1. True
  2. False

hintHint:

Photosynthetically Active Radiation (PAR) is the light wavelength range that is best fit for photosynthesis to occur. Photosynthesis is a process that requires light energy and optimally occurs in the 400 to 700 nanometer (nm) range 1.

The correct answer is 'False'.


    • Around 50% of the total radiation from sunlight falls under photosynthetically active radiation and supports the process of photosynthesis.
    • It constitutes the light of 400-700 nm wavelength which is absorbed by chlorophyll pigment. Out of which only 2 - 10% are captured by plants.
