A light ray, traveling parallel to the axis of a thin concave lens, strikes the lens near its midpoint. After traveling though the lens, this ray emerges traveling obliquely to the axis of the lens
A)such that it never crosses the axis.
B)crossing the axis at a point equal to twice the focal length.
C)crossing the axis at a point equal to one-half the focal length.
D)passing between the lens and its focal point.
E)passing through the focal point.
