1. the probability of finding any one particular electron on any

  1. Feb 21, 2012 #1
    1. the probability of finding any one particular electron on any finite interval in the universe is nonzero....does that imply that a string is as long as the universe?

    2. why do strings only vibrate at certain frequences?

    Re: strings

    I have not had any course or study, but here's my commonsense, not necessarily right.:smile:

    2. why do strings only vibrate at certain frequences?

    -May be they have something like natural frequence associated with their certain properties.
    -Or the frequency is itself quantised like the energy levels in atoms because energy is associated with the frequency.
