What ie photoelectric effect |
|
Answer» Under the right circumstances light can be used to push electrons, freeing them from the surface of a solid. This process is called the\xa0photoelectric effect\xa0(or\xa0photoelectric emission\xa0or\xa0photoemission), a material that can exhibit this phenomena is said to be\xa0photoemissive, and the ejected electrons are called\xa0photoelectrons; but there is nothing that would distinguish them from other electrons. All electrons are identical to one another in mass, charge, spin, and magnetic moment. The\xa0photoelectric effect\xa0or photoemission is the production of electrons or other free carriers when light is shone onto a material. Electrons emitted in this manner can be called photoelectrons. |
