9. In this manner, the intensity of the hght was recorded as a vertical 

 deflection and time was measured by means of the sweep along the 

 X axis. A typical oscilloscope trace is given in Fig. 4. The final portion 

 of the reaction is quite slow and was followed by periodic readings 

 with a millivoltmeter 8. A typical intensity versus time curve is given 

 in Fig. 3. Graphical integration of the total quantity of light emitted
