Simulations

• Blackbody Radiation: Use this applet to gives a good qualitative visualization of different radiation distributions determined by Planck's Law.
• Photoelectric Effect: Vary intensity, wavelength and voltage to see the photoelectric effect in three different materials, sodium, cesium, and silver. Be able to answer the questions of the type that appear at the bottom of the page.
• Photoelectric Effect: Stimulates an experiment for the determination of the Planck constant and the work function.Allows you to vary the cathode's material, the wavelength and the retarding voltage.
