Variation of Light Intensity

Compare the variation in intensity of light from different light sources. Use a light sensor to record and compare incandescent versus fluorescent light...

College / Physics

Light Intensity vs. Distance

The relative light intensity versus distance from a point light source is plotted and compared to theory.

College / Physics

Polarization of Light

The plot of light intensity versus angle between two polarizers is fitted to the square of the cosine of the angle, verifying the Law of Malus.
