3 ~ Introduction : For this experiment we will observe light passing through crossed polarizing filters. The light will be a red laser of light from a fixed location. We will observe the intensity of this light using computer equipment. We will also measure the light escaping through the two polarizing filters as a function of the angle between the axes to compare them to Malus’s Law. Experimental Set-up : We will use the LabPro interface connected to a light sensor and the computer to detect the intensity emitted from the red laser. The information will be collected and logged using the Logger Pro software on our computers. Out light source will be fixated on a rail system as well as our 2 polarizing filters with marked axes. The set-up will look similar to the one pictured below. Preliminary Questions: 1. When placing one polarizing filter on top of the second and turning one of them 90 degrees to one another, they appear to block all light traveling through. 2.
