Electromagnetic waves and electrons

  1. Oct 17, 2013 #1
    Does the electron emit electromagnetic waves?

    Which electron?

    A normal electron

    There is no such thing as "normal electron". All electrons are identical. However, depending on what they do, they either will, or will not emit electromagnetic waves. Hence you have to explain "which electron" you mean.

    I mean any electron.

    When will the electrons emit electromagnetic waves?

    And what do you mean by ''which electron?'' Aren't all of the electrons identical?

    They are identical, but an electron in an atom behaves differently from an electron in a cyclotron. So, which electron do you mean?

    I mean an electron in an atom

    Not in a cyclotron

    Then the short answer is "no".

    Longer answer is - it again depends. If the electron just occupies its orbital, it doesn't emit anything. If, for whatever reason, it jumps between orbitals - it either emits, or absorbs energy, typically in the form of EM radiation.

    How can an electron jump between orbitals?

    When it gets excited.

    Sorry, but apparently instead of starting learning from a book and asking questions when you don't understand something, you decided we are your teachers.

    We are not. EOT.

    Please do some reading on your own before asking overly broad questions here on the PF. We expect folks to put in some effort first to try to answer their own question. Here is a wikipedia page with much of the information you are asking about:

    http://en.wikipedia.org/wiki/Atomic_orbital

    If you have *specific* questions about that reading, or about other sources of information on the subject, please ask them here, and show us what you have been reading.
