Observing the emission spectra from LED's

The LED apparatus. You can make your own using a breadboard or
purchase this version through Ztec Co
 
The voltmeter is used to determine the turn on voltage of the LED.
Relating the turn on voltage to the emitted light frequencies produces a linear
graph whose slope is Planck's constant.

One computer simulation allows students to try different methods of modeling
the energy levels of a material that would produce the spectra observed in the lab.

Other simulations allow students to connect between the double-slit diffraction
experiment and the wave nature of matter.
 
How an infrared detector works was explored by observing its behavior when
exposed to ultraviolet and infrared radiation.
