Ray 1 approaches parallel to the axis, ray 2 strikes the center of the mirror, and ray 3 approaches the mirror as if it came from the focal point. When an object is placed in between focus and pole, a virtual and erect image is formed. To find this Virtual, erect, and diminished images are always formed with convex mirrors, irrespective of the distance between the object and the mirror. helps to trace the path of the light for the person to view a point on the image of an object. Table: Summary of images formed by a concave mirror. On extending backwards, these rays appear to intersect each other at point A’ behind the mirror. Concave MirrorConvex MirrorImage Formation By Concave MirrorConcave Mirror Ray DiagramImage Formation By Convex Mirror, A mirror is a surface that reflects a clear image. When the object AB is placed between the centre of curvature and principal focus, then the ray AD running parallel to the principal axis and another ray AE passing through the principal focus F intersect each other at point A’ beyond the centre of curvature. A mirror is a surface that reflects a clear image. Ray diagram helps to trace the path of the light for the person to view a point on the image of an object. When the object AB is placed at the centre of curvature C, then a ray of light AD which is parallel to the principal axis and another ray AE which pass through the principal focus intersect each other after reflection at point A’ just below the position of the object. Light converges at a point when it strikes and reflects back from the reflecting surface of the concave mirror. Thus the image formed in this case is behind the mirror, highly enlarged, virtual and erect. Ray diagram used arrow type lines to represent the incident ray and the reflected ray. By changing the position of the object from the concave mirror, different types of images can be formed. Image Formation in Concave Mirrors While drawing images of the object we benefits from the special rays given above. Check your score and answers at the end of the quiz, Visit CoolGyan for all Physics related queries and study materials, Guidelines for Rays Falling on the Concave and Convex Mirrors. So, the image formed by the concave mirror can be small or large and it can also be real or virtual. It also helps to trace the direction in which light travels. Different types of images are formed when the object is placed: At the infinity; Beyond the center of curvature; At the center of curvature; Between the center of curvature and principal focus; At the principal focus Test Your Understanding and Answer These Questions: Rules for obtaining images formed by spherical mirror, Rules for Obtaining Images by Spherical Mirrors.
