To Determine the V-I Characteristics of an LED and Calculate the Wavelength of the Emitted Light “OR” Determination of Planck’s Constant using LED

Here is the Experimental File in pdf format.

If you want to determine the value of Planck’s Constant using LED. Here is just a little modification in the calculations. Rest experiment is the same.

  In that case, no calculation, and you only observe V-I values for LED in forward and reverse bias.
