Which rules of ray tracing apply to converging lenses? Check all that apply. a A ray that comes through the focal point on the way to the lens will refract and travel parallel to the principal axis on the other side. b A ray that comes into the lens parallel to the principal axis will refract through the lens and travel through the focal point. c A ray that passes through the center (i.e. the principal axis) will continue traveling in that same direction. d A ray that passes through the center of the lens and then parallel to the optical axis on the other side of the lens
