Question

what relation is used to determine the Planck's Constant using LED​

Answer 1

Answer:

Experimental determination of Planck's constant h = 6.626×10−34J· s is performed using Light Emitting Diodes (LEDs). Spectropho- tometry and basic circuit analysis techniques are employed to obtain empirical data with respect to the energy of the emitted photons of light and thus used to calculated Planck's constant
