V. Readthe passage carefully and then answer the questions
To understand what a laser is, one has to understand how light is generated. Light comes from the electrons that surround the nucleus of every normal atom. When the atom of sodium is in its unexcited state, the electrons that surround the sodium nucleus are in their normal energy levels. If this sodium atom absorbs some energy from outside, one or more of the electrons will jump from a low energy level and orbit to a higher energy level and orbit. The atom then remains in this excited state until it is able to release the energy that it has temporarily stored. When the release occurs the electrons in the high energy level fall back to the low energy level. But as it does so, it emits the extra energy as a pulse that we may see as light. A possible jump of each of the electrons round the sodium nucleus has an exact amount or quantum of energy associated with it.
The word "LASER" is an acronym. The letters of the word come from "Light Amplified Stimulated Emission of Radiation". The laser beam is made by exciting the atoms of a suitable material - ruby is one - until most of the atoms have electrons orbit in a higher energy level than usual The excitation is then stopped and all the excited electrons fall back together to their normal orbits, and emit a pulse of light of the same energy. In this way, an intense beam of light is generated for a very short time. Every pulse in this beam is in step with every other pulse. A beam of light that is both monochromatic and coherent is obtained.
Laser beams carry surprisingly intense amounts of energy and so they can be dangerous to living tissues. The tissue absorbs the light in the beam and converts it into heat. If heat is generated in living tissues more quickly than it can be dissipated, then local heating of the tissues will occur. This local heating can be severe enough to kill the cells that the beam impinges on. Therefore, it is necessary to protect the human eyes that are very sensitive to this kind of damage when laser beams are being used. The damage can be done very quickly so protection from accident is very necessary.
36. What does the acronym LASER come from?
37. To understand what laser is, what should one do first?
38. How are the electrons when the atom of sodium is in its unexcited state?
39. Why are laser beams dangerous to living tissues?
40. What are the suitable materials to make laser beams that are referred in the text?

Soon they are capable of noting that they have placed. five knives, spoons, and forks on the tabl
