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.]
