what causes shadow length?

The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.
