Plants make food using photosynthesis. This food is important for the plants themselves and for organisms that feed on plants. Getting optimum rates of photosynthesis produces maximum plant yields.

Light intensityunit

This is because as the distance away from a light source increases, photonsclosephotonA packet of energy of light and other forms of electromagnetic radiation. of light become spread over a wider area.

There is an inverse relationship between distance and light intensity - as the distance increases, light intensity decreases.

For each distance of the plant from the lamp, light intensity will be proportional to the inverse of the distance squared (d2)
