Atomic emission is a process occurring when electromagnetic rays is emitted by excited atoms or ions. In atomic emission spectrometry the test is put through temperature ranges high enough to cause not only dissociation into atoms, but also to cause significant amounts of collisional excitation and ionisation of the test atoms to take place. Once the atoms and ions are in the ecstatic expresses, they can decay to lessen state governments through thermal or radiative (emission) energy transitions and electromagnetic radiation is emitted. An emission spectrum of an element includes several more lines than the matching absorption spectrum.
FES (previously called fire photometry) is at principle just like emission spectroscopy, with flame as the source of excitation energy (fire atomiser).
It is true that teenagers are quick to follow anything round the world which shows up 'hip' or 'in'. It really is in their mother nature to desire to be like young people in other parts of the world. They are quick to relate and to follow what they think is popular. By fashion, are included dress, flavor in music, words, hair styles, drug-taking and even moral ideals. Except in the most traditional of societies, it is impossible to control the arriving of fashion from other countries. With television, books and mags bring so easily available, the world has shrunk and what's uncovered as 'fashion' in a single part of the world spreads like wildfire everywhere else.
Youth, usually known as teenagers, are rebels because of restlessness within. They want to assert their individuality and the values of these peers, and break from the influence of these parents and their parents' generation.
