Homework Help: Uncertainty Principle in term of Angular Momentum

  1. Oct 24, 2006 #1
    I need to prove that the uncertainty principle can be expressed in the form

    delta L * delta theta = hbar/2

    where delta L is the uncertainty of the angular momentum and delta theta is the uncertainty in angular position.

    I know that L = m*v*r and I think I can express theta as x/r. But I really don't know where to go on this.

    Nevermind, I've got it. I'm a bit slow on the uptake today
