How To Draw Ray Diagrams Convex Lens Ray Diagrams Class ођ Rule 1 ray parallel to principal axis will pass through focus after reflection. for a concave mirror, we see that ray passes through focus after reflection. for a convex mirror , since focus is on the right side, it appears that ray passes through focus after reflection. Rule 2 ray passing through focus will become parallel to principal axis. for a convex lens, we see that ray passing through focus on left becomes parallel to principal axis after refraction. for a concave lens , since focus is on the right side, it appears that ray passes through focus, and then it becomes parallel to principal axis.
Ray Diagram Concave And Convex Lenses By Animation Tricks To Remember A plane mirror is a flat, smooth reflective surface with a clear, undistorted reflection. when an object is reflected in a plane mirror, it always forms a virtual image that is upright, of the same shape and size as the object. on the other hand, a spherical mirror exhibits a consistent curvature. it possesses a constant radius of curvature (in. Case 1 object is placed at infinity. in this case, object ab is kept far away from mirror (almost at infinite distance) so, we draw rays parallel to principal axis. since ray parallel to principal axis passes through the focus. both rays meet at focus after reflection. hence, image is formed at focus. and it is very very small. we can say that. Answer: since, the focal length of the lens ( 10 cm) is positive, it is a convex lens. (1) if an object is kept at 25 cm from the lens, the image will be real, inverted and smaller than the object. (2) if an object is kept at 5 cm from the lens, the image will be virtual, erect and larger than the object. The ray diagrams for the image formation in a convex and concave lens for a few positions of the object are shown below. rule 1: a ray of light from the object, parallel to the principal axis, after refraction from a convex lens, passes through the principal focus on the other side of the lens. in the case of a concave lens, the ray appears to.

This is the third video showing how to draw ray diagrams we have started a new series of videos on lenses, chapter 7 class 10 science and technology part 1. cbse exam, class 10. Convex lenses. when an object is placed at infinity, the real image is formed at the focus. the size of the image is highly diminished and point size. when an object is placed beyond the centre of curvature, the real image is formed between the centre of curvature and focus. the image size will not be the same as the object.
