How to distinguish the natural light from the polarized

The human eye is unable to distinguish the polarization of light. The same applies to most cameras, camcorders and cameras. To determine if the polarization of light polarizing filters are used.

How to distinguish the natural light from the polarized

Instruction how to distinguish between the natural light from the polarized

Step 1:

The polarizer is not intended for converting polarized light into, and to determine whether it has the polarization is called analyzer. The name is arbitrary, since by design it is no different from any other polarizer. To acquire this physical instrument, take any the failed device with a liquid crystal display, it is desirable that a major. Suit, for example, the large digital clock or calculator. Remove the batteries from the unit, disassemble it, and then remove the lamp. If you've seen a calculator or watch an old design, the polarizer is a film, which is separate from the display easily. In the modern machine it will have to carefully peel (do not break the indicator not to cut yourself). Then, under warm water to remove the glue from the polarizer.

Step 2:

Another good source of polarizing filters serve as sunglasses, but not all, and having a polarizing glass. In the selection of glasses in the store look through them on a glowing screen cell phone (it should be a liquid crystal - OLED or AMOLED is not suitable). If in this case you will see a colored stains, changing when you turn on the screen of glasses, these glasses are suitable for carrying out the experiments. Disassemble or otherwise alter them this is not required.

Step 3:

At the grocery store look at the device for authentication, hanging on the neck of some bottles of alcoholic beverages. After purchasing bottles customers often remove these devices and leave them at the cash tables. Take there one of them, disassemble, and then detach from the polarizer thin polymer film. Rinse with warm water and a polarizing filter glue. Do not bend it because it is fragile.

Step 4:

To determine whether the light is polarized, look at its source through a polarizer. Rotate it in its own plane. If a picture with the changes, the light is polarized. If the light is so bright that just looking at him dangerously, swipe experience looking through the filter illuminated by this source matte surface.
