A ray passing through the principal focal point of the lens will proceed parallel to the centre line upon exit from the lens. CBSE Class 10 Science Lab Manual Experiment – 4 Aim To determine the focal length of (i) concave mirror (ii) convex lens by obtaining the image of a distant ob...
State the characteristics of an image formed by a concave lens. 02:10 In the case of image formation by a concave lens , what can you say a... 03:41 Draw a ray diagram to show image formation by a concave lens. 03:15 State the Cartesian sign convention for refraction of light (ima...
Rays travelling parallel to the principal axis of a concave lens diverge after refraction in such a way that they appear to be coming out of a point on the principal axis. This point is called the principal focus of the concave lens.
convex mirrors and concave mirrors. We will also delve into the concept of ray diagrams, which help us understand how light behaves when it interacts with these mirrors. By examining the ray diagram of a spherical mirror, we can gain insights into the fascinating phenomena of reflection and ima...
