Energy vs. Wavelength; Psuedo-Photoelectric Effect

Demo Number 260
Location Shelf 45
Description Different colors of LED lights of similar intensity are shone on a phosphorescent sheet and the amount of glow is compared.
 Related Demos
  • Shorter wavelength lights are much more effective at illuminating the sheet than long-wavelength lights. Below a certain threshold, the light cannot make the sheet glow at all no matter how long it shines, analogous to the photoelectric effect.
