Planck's Constant from an LED

Statement of Purpose
With the ideas from diffraction, this experiment will show evidence supporting planck's constant.

Procedure 


Setup an L-shape for simple Pythagorean math use.

 Measure the distance of spectra.





Data



The white light is actually a combination of the 4 wavelengths from the colored LEDs. Which explained the gaps in the spectrum.


Conclusion
The small angle approximation makes calculation and measuring much simpler.
