why is it that when we change the light from un polarized to polarized light the intensity goes to half its value and is the polarization only have to the electric field and why?? thank you
When light is unpolarized, its electric field oscillates in all directions. However, when light is polarized, the electric field only oscillates in one direction. This can cause certain materials, such as crystals or plastics, to absorb the light differently depending on its polarization, resulting in a change in perceived color.
Polarized light can significantly reduce glare, especially from surfaces such as water, glass, or snow. This is because polarized filters block light waves that are oscillating in certain directions, which are typically the waves responsible for creating glare.
No, polarized light itself is not harmful to our eyes. In fact, polarized sunglasses are often recommended for activities such as driving or being near water, as they can reduce eye strain and improve clarity. However, some polarized filters may block out certain wavelengths of light that are important for vision, so it is important to choose high-quality polarized lenses.
Polarized light can enhance the visibility of certain objects, especially those with reflective surfaces. This is because polarized light can reduce glare and improve contrast, making objects appear sharper and more defined.
Yes, polarized light is used in various scientific and technological applications. For example, polarized light microscopy is used in biology and materials science to study the structure and properties of different materials. Polarized light is also used in LCD screens, 3D glasses, and various measurement tools.
