Refraction of Light by convex lens
1. A ray of light traveling parallel to principal axis of convex lens, after refraction, passes through the focus of lens.
2. A ray of light passing from focus of a convex lens, after refraction from the lens, travels parallel to principal axis.
3. A ray of light passing from the optical centre of a convex lens, after refraction from the lens, travels in a straight line without deviation.
