Streams of protons and electrons emitted from the Sun produce?
The stream of protons and electrons being emitted from the sun is called the solar wind.
Why do astronomers say that the spectral lines produced by an element are like fingerprints?
The energy levels of an atom are the distinctive property of that atom. The difference in energy levels determine the amount of light that could be emitted or absorbed. There is no same energy level difference from one atom to another, therefore spectral lines are referred to as an "atom's fingerprint". The spectral lines make atoms unique, just as fingerprints make people unique, no two humans have the same fingerprints.
What form of energy emission accompanies the return of an excited electron to its ground state?
What form of energy emission accompanies the return of excited electrons to the ground state?
What type of spectrum is produced when the light emitted directly from a hot dense object passes through a prism?
Its called atomic spectrum
What is the source of atomic emission spectra?
In an atom of any element there are electrons in the valence shell . Each shell has a fixed no of sub shells that are characterized by specific quantum nos. So this holds true for the valence shell also . Depending on the distance of the valence electrons from the nucleus and its electro static effect on the valence electrons these valence electrons absorb energy from any high energy source that comes in its proximity. Now the entire atom has become a high energy species but by the law of thermodynamics(and nature )every body in the universe tends to have minimum energy and achieve stability. So these high energy electrons tend to emit the absorbed energy and come back to a lower energy state for maximum stability .In the process the emitted energy is observed as spectral lines in a spectrometer .These spetral lines together form what we call as emission spectrum
What is spectral radiancy?
Power emitted from a unit area of a particular temperature
What evidence convinced J.J Thomson that an atom consist of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
What evedence convinced JJ Thomson that an atom consists of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
What is meant by the term spectral emission?
Refers to the color of light emitted by a phosphor.
Streams of protons and electrons emitted from the Sun produce?
The stream of protons and electrons being emitted from the sun is called the solar wind.
When 10 electrons drop from fifth to second energy level?
Only one photon is produced per electron in any de-excitation. The number of energy levels it drops only determines the energy of the photon emitted.
Do stars produce the lights that they give off of?
Yes, the energy produced when nuclear fusion occurs. Hydrogen atoms form helium atoms. The resultant energy enables electrons to be freed from nuclei. As these electrons return to the nuclei energy is emitted.
What does line spectrum tell us?
The bright line emission spectrum tells us the amount of energy between the exited and ground state. When electrons move from an exited state to a ground state, radiant energy of a specific frequency is emitted this creates spectral lines.
Why do salts produce colors when heated?
The cause of the color is light (specific spectral lines) emitted by the metal from the salt at high temperatures.
Can an animal see electrons emitted by a cathode ray tube?
no
Will exposure to red light cause electrons to be emitted from cesium?
No. It will not.
Will exposure to blue light cause electrons to be emitted from cesium?
No
