for an electron characteristic of the element, also called the work function (W0). When a photon strikes a bound electron, it transfers its energy to the electron. If this energy is less than the metal''s work function, the photon is re-emitted and no electrons areliberated. If this energy is greater than an electron''s binding energy, the electron escapes from the metal with a

1. Photoelectric effect

In this experiment, the light from a Hg vapour lamp is spectrally filtered by an interference filter and illuminates a photocell. Inside the photocell there is a metal coated cathode. The annular anode is placed opposite to the cathode. When a photon of frequency strikes the cathode, then an electron can be ejected from the metal (external photoelectric effect) provided the photon has

The Photoelectric Effect

The objective of this experiment is to demonstrate the quantization of energy in electromagnetic waves and to determine Planck''s constant h. You will measure the maximum kinetic energy of electrons ejected by the photoelectric effect from an alkali metal surface as a function of frequency. A constant offset in energy is caused by the work function φ of the metal cathode,

What are the basic characteristics of a photocell?

The basic characteristics of the photocell were tested and analysed through experiments by an optical control experimental platform, such as short circuit current, open circuit voltage, illumination characteristic, volt ampere characteristic, load characteristic, and spectral characteristic.

How to test a silicon photocell?

Open Circuit Voltage Characteristic Test of Silicon Photocell. Under the condition of the Fig2 circuit, the illuminance on photocell is controlle d by illumination meter. Adjust illumination to the meter, at this time the meter readings should be 0. Open the power supply, adjust the illumination read out the voltmeter reading, and fill in table 2.

How to measure photocell current?

Diagram: Procedure: 1. Give a supply of 220V to the lamp. 2. Switch on the lamp and move the lamp from extreme position towards photo cell, there will deflection on micro ammeter at certain distance. Record this distance “d” and reading of photocell current ‘I’ from Metal + - RL d A Semi conductor Light source docsity.com micro ammeter.

How does a photocell function?

A photocell functions by emitting electrons from the back, which is coated with potassium, when light shines on it. The photoelectric effect was studied under more controlled conditions using a photocell instead of the electroscope experiment.

How do I adjust the nanoammeter reading in a photocell?

Keep the exit-slit of the lamp enclosure along the same line and facing the entrance-slit of the phototube enclosure. For the first part of the experiment (Table 5. Close the photocell entrance-slit and adjust the nanoammeter reading to ~ zero using the ‘Zero adj.’ knob.

What is a commercial photocell?

A commercial photocell, such as model number 926e, features a disc mounted to one side and at right angles to the emitter. This arrangement allows the photocell to be illuminated without illuminating the collector.
