Refraction of Light Class 10




Image Formation in Lenses Using Ray Diagrams

  • Ray diagram helps us to study the nature, position and relative size of the image formed by lenses.
  • For drawing ray diagrams we first consider how light rays falling on both concave and convex lens in three different ways get refracted.
  • First consider the case for convex lens
    image formation by convex lens
  • Secondly consider the case for concave lens
    image formation by concave lens

  • The ray diagrams for the image formation in a convex lens for a few positions of the object are summarized below in the table
    ray diagrams for the image formation in a convex lens
  • The ray diagrams for the image formation in a concave lens for a few positions of the object are summarized below in the table
