Image formed by a concave mirror when the object is placed at infinity When the object is placed at infinity, the two rays AB and DE running parallel to the principal axis get reflected at point B and E respectively and intersect each other at the principal focus F on the principal axis. Object at infinity: When the object is at the infinity, a point sized image is formed at principal focus behind the convex mirror. Table 6: Rules for image formation by convex mirrors. Question 2 The image formed by a convex mirror is seen to be erect,virtual and diminished.What is the position of the object? At 2F 4. Now ( 352 ) and ( 358 ) (with ). Image Formation By Convex Mirror The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. bringing your face close to mirror. The image is smaller in size as compared to the object but gets larger when the object gets closer to the mirror. Beyond 2F 3. Images formed by convex mirror using ray diagram (1) Object is between infinity and pole (a) Image is formed between pole and focus. Location of the image is always between the focal point and vertex of the mirror. At infinity 2. In this section, let us look at the types of images formed by a convex mirror. (b) It […] The images formed through a convex mirror cannot be projected on a screen as it is contained inside the mirror. LIVE EXAMPLE You can distinguish between these mirrors just by looking into them i.e. In convex mirrors image is usually formed behind the mirror, it is virtual and erect. Convex mirror is used as the rear mirror of the vehicles because, the convex mirror enables a driver to view large area of traffic behind him by forming a small image of the vehicles. Table 6 shows how the location and character of the image formed in a convex spherical mirror depend on the location of the object, according to Eqs. Question 1 Mention few applications of convex mirror? Between the focus F and optical centre C 1. … Image Formation by Convex Mirror There are only two possibilities of position of object in the case of a convex mirror, i.e. At the focus F 6. Between F and 2F 5. object at infinity and object between infinity and pole of a convex mirror. We will now discuss the formation of different types of images by a convex lens when the object is placed 1.
