Light scattering and polarization
The direction of light scattered off small particles has a strong dependence on the polarization of the incoming light. In this experiment you will measure that polarization dependence.
The experiment involves low-intensity measurements that can be easily swamped by the ambient light environment, so the experiment uses a lock-in amplifier to isolate the desired signal.

There is also a relevant simulation of radiation due to an oscillating charge here.
