    [pic], where c is the speed of light in vacuum and v is the speed of light in the substance. For example, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in vacuum as it does in water. (See typical values for different materials here.) The historically first occurrence of the refractive index was in Snell's law of refraction, n1sinθ1= n2sinθ2, where θ1 and θ2 are the angles of incidence of a ray crossing the interface between two media with refractive indices n1 and n2...

  • Fruit Ripening

    are some fruits sweet and some sour, whereas others have no specific taste? Naturally fruit contains cellulose, proteins, starch, proteins, vitamins, certain acids and fructose (or sugar). When fruit ripens, a series of chemical changes occur in the fruit that result in either a sweet fruit, sweet and sour fruit, sour fruit or fruit with no specific taste. During these changes, the acids content in fruit becomes less and the fructose content increases thereby resulting in a sweet fruit (Coen...

Fruits contain fructose, acids, vitamin, starch, proteins, and cellulose. All of these components contribute to the taste of fruit. Fruits with high fructose levels tend to be sweeter whereas fruits with high levels of acid tend to be sour. Oranges however, have equal quantities of fructose and acids...

  • Fruit Ripening

     Placing fruit in a bag will help hasten the ripening for only a few fruits. Most fruits will not ripen (ever) once they have been picked. The only fruits that ripen once they're picked are bananas, avocados, pears, mango, and kiwifruit. Ripeness in fruits is based on sugar content, not color, thus most tomatoes in grocery stores have no flavor because they were picked green and exposed to ethylene gas to induce color change. Tomatoes are what are known as a "climacteric fruit" which means they'll...
