18.4. Experimental Procedure¶ · Turn on the mercury lamp and wait for about 5 minutes until it reaches its full intensity. · Connect the second multimeter to ...

An adjustable voltage Vca is applied between the cathode and anode, and the photocurrent Iph is measured indirectly by one of the multimeters on the workbench.

The key experimental facts about the photoelectric effect are the following. ... Procedure: Activity 1: Measurements of the h/e Ratio and the Work Function ...

In the experiment you will measure the retarding potential required to stop the photoelectric current as a function of frequency, or reciprocal wavelength: c = ...

On one graph, plot the voltage versus galvanometer readings for each filter and draw the best smooth curve that fits the data for each of the filters. Identify ...

In this lab, you will investigate the particle nature of light through the photoelectric effect, and make a measurement of the value of Planck's constant.

1. Describe the effect that passing different amounts of the same colored light through the Variable Transmission Filter has on the stopping potential and thus ...

A typical photoelectric effect experiment uses an evacuate glass vessel with an anode of work function φ connected in series to a power supply and an ammeter.

The photo cell is used to demonstrate the photoelectric effect. When the photocathode is irradiated with light, electrons are liberated from.

In this experiment you will measure the photoelectric current from an alkali metal surface as a function of a re- tarding potential that opposes the escape of ...
