| Applications of Polarized Light |
|
Polaroids are used in sun glasses. They reduce the intensity and the glare by cutting down the horizontally polarized light. |
| |
|
Polarized light is used in photo elastic stress analysis. |
| |
|
For 3-D view, special type of glasses, which have
polaroids with perpendicular axes, are used. |
| |
|
Polarized light is useful to determine size and shape of viruses. |
| |
|
This polarized light finds many practical applications in industry and engineering science. |
| |
|
| |
| Polaroids polarize light. A number of needle shaped crystals quinine iodosulphate with their axes parallel to one another are packed between two sheets of plastic. This arrangement serves as the polaroids. |
| |
| The important uses are: |
| |
|
These reduce excess glare and hence sun glasses are fitted with
Polaroid sheets. |
| |
|
These are also used to reduce headlight glare of cars. |
| |
|
They are used to improve
color contrast in old oil paintings. |
| |
|
These are useful in 3-D motion pictures i.e., holography. |
| |
|
Wind shields of automobiles are also made of
Polaroid sheets. |
