Why does light still pass through when you have three filters and the first is vertical the second is rotated and the third is horizontal?
Polarization of light refers to the direction in which the electric field oscillates as the light wave travels. This direction can be either vertical, horizontal, or at any angle in between.
Light can become polarized through various processes such as reflection, scattering, and transmission. For example, when light reflects off a smooth surface, the reflected light becomes polarized in a specific direction.
Polarization of light is important in many scientific fields, including optics, astronomy, and biology. It allows us to study the properties of light and understand how it interacts with different materials and substances. In astronomy, polarization can help us detect magnetic fields in stars and galaxies. In biology, it plays a role in vision and communication between organisms.
Yes, all types of light, including visible light, infrared light, and ultraviolet light, can be polarized. However, the degree of polarization may vary depending on the source of light and the medium it travels through.
Polarization of light is used in various technologies, such as LCD screens, 3D glasses, and polarizing filters for cameras. In LCD screens, the polarization of light is controlled to create images and colors. In 3D glasses, different polarizations are used to create the illusion of depth. And in cameras, polarizing filters can be used to reduce glare and enhance colors in photographs.
