Light has some interesting properties, many of which are used in medicine. 1. The speed of light changes when it goes from one material to another. The ratio of the speed of light in vacuum to its speed in a given material is called the index of refraction. If a light beam meets a new … Read more
Light is an electromagnetic radiation. Although light is only a tiny part of the electromagnetic spectrum, it has been the subject of much research both in physics and in biology. The importance of light is due to its fundamental role in living systems. The sun is still the major source of light in the world. … Read more
As already mentioned above, the electric force between two particles decreases with the inverse square of the distance, just as does the gravitational force. Coulomb, who investigated the repulsion between small balls charged by rubbing, discovered the dependence of the electric force on distance through experiments. His experimental results are summarized in coulomb’s Law – … Read more
