Notes for Planck's Constant lab

1) The purpose of this lab is to determine Planck's constant using light emitting diodes.

2) Complete this table:

Color  Wavelength  Voltage  Frequency    Energy
         (nm)        (V)    (10^14 Hz) (10^-19 J)
--------------------------------------------------
Red       660
Orange    620
Yellow    587
Green     570
Blue      468
--------------------------------------------------

3) Make a graph of energy vs. frequency.
4) Draw the line of best fit.
5) Determine the slope of the line.
6) State the value of Planck's constant you determined.
