According to the ray diagram, the ray of light will pass through point 2 after passing through the lens. This is because the ray parallel to the principal axis will pass through the focal point after passing through the lens, and the ray through the center of curvature will continue in the same direction after passing through the lens. The point at which these two rays intersect is point 2.
