Photoelectric Effect Trainer

Photo-Electric Effect : photo current versus intensity and wavelength of light; maximum energy of photo-electrons versus frequency of light.

The experimental setup helps to study the photoelectric effect :

  1. Variation of photocurrent versus intensity.
  2. Variation of photocurrent versus wavelength of light.

The setup consists of :

  1. Variable precision power supply : 0 to 1000 mV.
  2. Digital Voltmeter : 3 ½ Digit LED Display.
  3. Digital Microammeter :  3 ½ Digit LED Display.
  4. Digital Ammeter :  3 ½ Digit LED Display.
  5. Variable Lamp Intensity Controller.
  6. Lamp Current Measurement by Ammeter.
  7. Phototube with enclosure.
  8. Halogen lamp with enclosure.
  9. Set of Colour Filters [4 nos.]
