Question

Question 03
Which range of wavelength (in nm) is called Photosynthetically Active Radiation (PAR)?
(a) 100-390 (b) 390-430 (c) 400-700 (d) 760-100,00

Answer 1

(c) Photosynthetically Active Radiation (PAR) ranges from 400-700 nm. This is the visible range of light energy.
The range of other wavelength are associatic with
100-300 nm : Ultraviolet (UV) range
390-430 nm : Infrared (NIR) range
760-100,00 nm : Mid Infrared (MIR) range
