Experimental value of planck's constant

[fattykeong]

Can i know what may account for the difference between our experimental value of Planck's constant and the accepted value of it?
Did anything related to the light effect(it surrounding when we doing our experiment)??

I don't understand the question. The accepted value is determined by experimental measurements so they agree within experimental error. What is your question exactly?

Are you doing error analysis? I guess you may have to go through the detailed procedure of ur experiment to look for any possible reason that may account for the error, i.e., the surrounding, the ways of measuring and recording, etc.
