All articles with unsourced statements Articles with unsourced statements from October Articles with unsourced statements from January And the fact that we see the sky hambjran blue, rather than violet an even shorter wavelength of light that experiences even more scatteringhas more to do with how the human eye evolved than anything special about blue light itself.

This was due to red iron-rich dusts thrown up in the dust storms occurring from time to time on Mars. Dengan cara ini, melanin melindungi lensa mata dari cahaya ultraviolet. Moreover, when these fields oscillate like this, they behave exactly like light—meaning that light gamburan a wave made up from these fields!

This means that once a molecule is polarized, the electrons wobble, too! In addition the oxygen in the Earth’s atmosphere absorbs wavelengths hambkran the edge of the ultra-violet region of the spectrum.


Mekanisme hamburan defek statis dan vibrasi termal terhadap The effect is further increased because the sunlight must pass through a greater proportion of the atmosphere nearer the earth’s surface, where it is denser. Graphene is amazing stuff, by the way…amazing enough that you should expect a whole post on it at some point. You have a gift for explaining technical topics both thoroughly and in an easily understandable manner.

As previously stated, Rayleigh scattering is inversely proportional to the fourth power of wavelength, so that shorter wavelength violet and blue light will scatter more than the longer wavelengths yellow and especially red light. For the brave, here is a mathematical treatment of Rayleigh scattering. When a molecule is polarized, the wobbling of the atomic bonds also drives the motion of the electrons. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency.

This removes a significant proportion of the shorter wavelength blue and medium wavelength green light from the direct path to the observer. Again, note the epic beard source.

A changing electric field produces a magnetic field, which produces an electric field when it changes, and so on. Jadi, melanin menyerap lebih kuat cahaya warna ultraungu ultraviolet daripada cahaya warna biru, dan menyerap warna biru lebih kuat daripada warna hijau.

Views View Edit History. So the sunlight is made of many colors. The glass itself lights up blue, but the light that comes out the front is orange. Lord Rayleigh won the Nobel prize for his discovery of Argon gas. He discovered an ingenious way to detect whether or not his air was sufficiently pure: Selain sebagai pelindung alami terhadap pancaran sinar atau cahaya yang membahayakan, zat melanin juga menyerap lebih kuat cahaya berenergi tinggi dari pada cahaya berenergi rendah.


There are also several videos on Youtube. Gives a brief history of theories of why the sky is blue leading up to Rayleigh’s discovery, and a brief description of Rayleigh scattering.

Kemudian menjalar melalui lensa hambudan membalikkan cahaya tersebut. Para peneliti yakin bahwa melanin yang ada pada mata dapat memberikan perlindungan dari pengaruh sinar matahari yang merusak, sekaligus meningkatkan ketajaman penglihatan. Hamburan dalam perspektif klasik dan kuantum Education. Kemudian membentuk gambaran balik pada retina.

So he has a Nobel biography too. Turner may owe their vivid red colours to the eruption of Mount Tambora in his lifetime.

An electron attracted to an atomic nucleus behaves much like a mass on a spring source.
