There were two lenses used in this lab; a bi-concave lens and a bi-convex lens. The main difference(s) between these two lenses is. O The radius of curvature of the the lens surfaces was significantly different for the two lenses. The distance from the lens to the focal point was significantly different for the two lenses. Incoming rays are bent toward the axis for one lens and away from the axis for the other. All of the above options are true
