The size of the image is much smaller as compared to the object. The ray diagram shows that the image of this object is located as a right-side up image positioned behind the mirror. Ray diagrams are necessary for understanding the formation of an image by a concave mirror. The ray passing through the focal point becomes parallel to the principal axis after refraction by the lens. Such images are called A point source of light B is placed at a distance L in front of the centre of a mirror of width d, hung vertically on a wall.A man walks in front of the mirror along a line parallel to the mirror at a distance 2 L from it as shown in the figure. Image formation in convex lens Case 1:When object beyond 2F: In this case image will form between F and 2F, image will be real, inverted, smaller than the object. In fact, it can be generalized that anytime the object is located between the focal point (F) and the mirror, the image will be located behind the mirror. Focal length: it is the distance between the pole and principal focus of the concave mirror. (image will be uploaded soon) A real image will be formed between the focus and centre of curvature, when the object is placed beyond the centre of curvature. In such cases, the image will be upright (not inverted) and larger in size than the object. Ray diagram for an object placed between 2F and F from a convex lens. The Ray diagram of case the object is between pole and focus of concave mirror is in fig 2 And the nature of the image is Ray diagram for concave lens. The size will be small as compared to the object. It is denoted by f. Concave Mirror Ray Diagrams. And the nature of the image is- same size, inverted and real. Concave Mirror Ray Diagram: When an object is at infinity, a real image is formed at the focus point. The greatest distance over which he can see the image of the light source in the mirror … Ray Diagrams for Concave Mirrors and its use Rakesh Rajak August 27, 2020 0 Comments For a Concave Mirror, an object can be placed at any position so that image is created at different - different positions. Case 2:When object is placed at 2F In a film or data projector, this image is formed on a screen. The Ray diagram of case the object is at the centre of curvature of concave mirror is in the fig 1. Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed: (i) at the centre of curvature of a concave mirror (ii) between the pole P and focus F of a concave mirror (iii) in front of a convex mirror (iv) at 2F of a convex lens (v) in front of a concave lens 1 See answer nellaiyappar2006 is waiting for your help.
