Using Polarized Color Lenses to Investigate the Composition of Light

Abstract:While experimenting with different types of light reducing glasses to minimize light sensitivity produced by a concussion, I found an interesting combination of lenses, which led me to investigate the science behind it. I discovered that by using polarized, dark glasses and a blue filter, it is possible to see LED bulbs as blue and incandescent light bulbs as purple. This led me to experiment with other combinations of lenses. No other combination of lenses had the same effect on light as the first combination and I found out that this could be used for many things.

- Do research on light and polarization.
- Inspect the color lenses (e.g., plastic or cellophane).
- Determine if the lenses were polarized or not. I did this by looking through the lenses at various angles while looking for a change of light in front of a light source, like a monitor.
- Use different combinations of the polarized lenses and the non-polarized lenses to see if there were any differences in how I perceived light from LED lights, incandescent lights, and candles.
- Analyze data
- Write conclusions
