orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The purity of the oil extracted from the oranges can be determined by physical properties such as optical rotation and refractive index. In this experiment‚ limonene will be isolated by steam distillation. Normally‚ big molecules such as limonene require very high temperatures to boil. In the presence of water‚ liquids which are immiscible with water

” - Wikipedia‚ the free encyclopedia Types of Illusions- 1) Visual Illusions 2) Optical Illusions “The terms visual illusion and optical illusion are often used interchangeably. Visual illusions demonstrate the ways in which the brain fails to recreate the physical world. However‚ unlike visual illusions‚ optical illusions do not result from brain processes. Instead‚ an optical illusion is the perception of a distortion that results from the physical properties of light‚ such

Optical Properties of Quasicrystals: Negative Refraction Quasicrystals‚ or crystals that display the unusual property of non-periodicity (while remaining ordered)‚ were discovered in the 1980s by Dan Shechtman. A highly controversial topic‚ Shechtman did not produce a paper describing them for over two years after their discovery. However‚ within the past 30 years‚ the scientific community has come to accept them‚ reproduce them for study‚ and even award Dan Shechtman with a Nobel Prize for their
