Wave interference and superposition

  1. Oct 19, 2011 #1
    hi everyone,
    i was wondering whether i can change this sentence ( if the phase difference changes rapidly , the average effect of no interference is recorded.) to( if the phase difference changes rapidly , the average effect of no superposition is recorded.)

    as i remember that the term "interference" is only used when there are constant phase difference between two source.

    thanks

    average is a powerful word - I don't really agree with the first statement, and so I can't say either would be ok to use. Although, interference is a particular case of superposition, but not all cases of superposition are interference. So I don't think those words are exactly interchangeable.
