Since momentum is a vector, I will have to plot one component of the momentum—just for fun, I will choose the x-coordinate. Here's what I get.

For example, imagine catching a ball. When the ball is moving, it has momentum. You have to exert a force with your hand to stop the ball (and bring its momentum down to zero).

The ability of light to carry and deliver orbital angular momentum (OAM) in the form of optical vortices has attracted much interest. The physical properties of light with a helical wavefront can be ...

Orbital angular momentum has the potential to transfer, manipulate and store information. They are made from the orbital angular momentum of electrons orbiting their atomic nucleus – and the study of ...
