Different between L^2 and L in Hydrogen atom

  1. May 29, 2012 #1
    I'm here got a small question,

    what is the different between L2 and L for the hydrogen atom.

    Do L2 means total angular momentum and L means angular momentum?:confused:

    Given that L2=l(l+1)ℏ2 and L=(√l(l+1))ℏ

    THX :smile:

    L is the (magnitude of the) angular momentum. L2 is the square of L which is more convenient to work with in some mathematical manipulations.
