I am doing water splitting experiment, I have to calculate Quantum efficiency for hydrogen evolution so how I can know the no. of incident photons coming from source.
(a) Did I have to put something inside my solution.
(b) How do I know the no. of scattered or absorb photons (any possibility to measure)
(c) Is that any instrument which will tell regarding flux (lux Meter) or actinometry. which is more apporpriate.

Actinometry is better than the use of Lux meter. Becuase actimetry gives the amount of light absorbed by the entire solution. While, Lux meter only give the intensity of the light. In must be different from that of the intensity absorbed by the solution. So, it's better to conduct actinometry.
