  1. Photosynthetically active radiation is represented by the range of wavelength of
    1. 340-450 nm
    2. 400-700 nm
    3. 500-600 nm
    4. 400-950 nm
Correct Option: B

Photosynthesis takes place only in the visible part (400 - 700 nm wavelength) of electromagnetic radiations. Hence this component comprises the photosynthetically active radiation.
