K.C.S.E Physics Q & A - MODEL 2004PP2QN07
a) i) What is photoelectric effect?
ii) You are provided with the following:
a photocell, a source uv light, a rheostat, a source of e.m.f, a milliammeter, a voltmeter and connecting wires. Draw a circuit diagram to show how photoelectric effect may be demonstrated in the laboratory.
b) In a photoelectric effect experiment, a certain surface was illuminated with radiation of different frequencies and the stopping potential determined for each frequency
Table 2 shows the results obtained.
(i) Plot the graph of the graph of stopping potential (y-axis) against frequency.
