Edgardo said:Nice experiment. Where do you get such polarizer lenses (camera filters?) ?
A while ago I opened some cheap calculators and took the polarizers from the LCD.
Haven't tried your experiment though. Maybe I will show it to my brother and sister
and (hopefully) impress them

Polarized light is a type of light that has its electric field oscillating in a specific direction. This results in a light wave that only vibrates in one plane, unlike ordinary light which vibrates in all directions.
There are many ways to have fun with polarized light that are inexpensive. Some examples include making polarized sunglasses, creating a homemade polarimeter, or using polarizing filters to view hidden images.
The materials needed will depend on the specific activity, but some common items include polarizing filters, light sources such as flashlights or lasers, and everyday objects like CDs or 3D glasses.
There are endless experiments that can be done with polarized light, such as studying the properties of different materials, exploring the concept of light polarization, or creating optical illusions.
Yes, it is important to never look directly into a light source, especially lasers, as they can cause eye damage. It is also important to handle polarizing filters carefully to avoid scratches and to not leave them in direct sunlight for extended periods of time.
