How to calculate amount of photons
WebLet's calculate the number of photons emitted per second from a 100 watt light bulb, and the no. of photons hitting the wall per second from a 5W/m^2 intensi... WebThe daily light integral (DLI) is the number of photosynthetically active photons (photons in the PAR range) accumulated in a square meter over the course of a day. It is a function of photosynthetic light intensity and duration (day length) and is usually expressed as moles of light (mol photons ) per square meter (m −2 ) per day (d −1 ), or: mol·m −2 ·d −1 .
