Apparently the human eye can see polarized light in nature.
An experiment to test the visual ability of the octopus that had to do and jellyfish revealed something new that has never recognized the man: see the polarization color.
The polarization property of others as the third light bright colors and describes the direction of oscillation in light waves.
Dr. Shelby Temple, seorang Peneliti Dari Ecology Vision Group in the School of Biological Sciences at Bristol bahwa menjelaskan umumnya Pada, Cahaya merupakan Gabungan polarisasi. Namun terkadang, sejumlah kiss Gelombang berosilasi kea rah give cahayanya sama Yang Akan terpolarisasi.
In several animal species such as bees and ants, the pattern of polarized light is used as a navigation tool. Very few people know that people become too has the same capacity when polarized light to see with the naked eye.
In a perspective of testability study on the polarization of light, scientists with the brush Haidingers a visual effect that will be placed at right angles to the polarization angle. Researchers then developed special effects filters or the percentage of polarized light to distinguish, that is, from 0 to 100 scale view percent as Haidinger brush, which can be seen by the eye human.
The result of 24 people, which is tested known that the polarization level of the average of 56 percent sensitivity.
Dr Juliette McGregor, one of the leaders of the study was explained, usually visual effects Haidinger brush, disappears quickly human eyes in seconds, once the new brain to recognize that reacts. This resulted in very few people are aware that they were capable of polarized light in daily activities to see. McGregor also noted that the results of this study show that the cornea of the human eye can immediately affect the ability of the eye to detect the polar light, however, varies the capacity of each individual eye.
