|
Answer» Evolution of gases, change of colour, formation of precipitate,energy change,change of state.. There are commonly six characters that chemical reaction show.. liquid water is boiled, it is still water; likewise frozen water, or ice, is still water. Melting, boiling, or freezing simply by the application of a change in temperature are examples of physical changes, because they do not affect the internal composition of the item or items involved. A chemical change, on the other hand, occurs when the actual composition changes—that is, when one substance is transformed into another. Water can be chemically changed, for instance, when an electric current is run through a sample, separating it into oxygen and hydrogen gas. |

Why a speed of light changes causes refraction ... Plzz help me .. P..r..I..ty |
|
Answer» Light is slowed down in transparent media such as air, water and glass. The ratio by which it is slowed is called the refractive index of the medium and is usually greater than one. My question is why speed of light is changes when going to other medium ... Your answer is not clarify this clearly.. Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. |
