If both source and listener are moving at the same speed and in the same direction, fLwill ------- .
If the source and the listener are moving toward each other, fL will ------- .
If the source and the listener are moving away from each other, fLwill ------- .
If the listener is following the moving source but at a slower pace, fL will -------- .
