This shows that , apart from an overall phase factor , the pulse travels along
undistorted in shape with a velocity , called the group velocity : ( 7 . 32 ) If an
energy density is associated with the magnitude of the wave ( or its absolute
square ) , it ...

where we have introduced a vectorial Alfvén velocity : ( 10 . 70 ) The wave
equation ( 10 . 69 ) for v , is somewhat involved , but it allows simple solutions for
waves propagating parallel or perpendicular to the magnetic field direction . *
