Answer:

HEYA

HERE IS YOUR ANSWER

The rate of photosynthesis is dependent on the wavelength of the the light which falls on the plant.

Explanation:

As a result of this whenthe light of higher wavelength falls on the plant the the rate of photosynthesis decreasesexponentially because photosynthesisis a first order Kinetic reaction.

Also only optimal range of wavelength is necessary for production of starch by the process of photosynthesis. this is because the chlorophyll is only suitable for observing a certain wavelength of light.
