GENERAL KNOWLEDGE

Detailed explanation-1: -Photosynthesis range from 400 to 700 nm, It absorbs the Violet, Blue and Red colour of Light. In white light all the colour spectrum energies are involved so, maximum photosynthesis is taken place in white light.

Detailed explanation-2: -In order to absorb the blue color of light in the greatest quantity, the maximum intensity of photosynthesis occurs in red light. So, the correct answer is, ‘Red light’. Note: Chlorophyll is a green-colored pigment that in plants absorbs light for photosynthesis.

Detailed explanation-3: -White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other colors.
