Light Reflection and Refraction - 18 | Image formation by spherical lenses | CBSE Class 10

CBSE Class 10 Science Chapter 10 - Light Reflection and Refraction - Image formation by spherical lenses involves 3 special rays: 1. Ray parallel to principal axis: Any light ray travelling parallel to the principal axis of the convex lens, after refraction always passes through the principal focus of the convex lens. 2. Ray passing through principal focus: All light travelling in such a way that they passes through the principal focus of the convex lens after refraction becomes parallel to the principal axis. 3. Ray passing through optical center: Any ray passing through the optical center does not deviate from its original path.
