WebbExperimental Apparatus The photoelectric effect in this ex-periment occurs at the cathode of an IP39 phototube. The phototube is constructed as shown in Figure 2. The IP39 phototube is designed to function as a diode where light, inci-dent on the tube, illuminates the cathode and causes photo -emission of electrons.

According to the classical theory, light is a wave and this effect would be explained to be due to transfer of light energy on to the Zinc plate. Increasing the intensity should therefore increase the kinetic energy of the ejected electrons. However, this did not meet up with the experimental observations which showed that light below a ... signs for cleaning up after yourselfWebbStep 1: Write out the photoelectric equation and rearrange to fit the equation of a. straight line. E = hf = Φ + ½ mv2max → Ek (max) = hf - Φ. y = mx + c. Step 2: Identify the threshold frequency from the x-axis of the graph. When Ek = 0, f = f0.
