The experiment models the emission of photons by a lamp, the absorption of those photons by a solute in a sample solution, and the detection of the photons by a photomultiplier tube. The photons are represented by little balls (a particulate matter model rather than a wave model). The simulation permits the simultaneous use of two different wavelengths.
The user may specify several operating conditions for the spectrophotometer.
To use the applet
- Select the desired sample.
- Start the simulation by clicking on the green button in the lower right corner of the applet.
- The intensity of photons reaching the detector may be measured using the timer in the lower left corner of the applet.
