Concave MirrorConvex MirrorImage Formation By Concave MirrorImage Formation By Convex Mirror. Case 5: The object is located in front of F. When the object is located at a location beyond the focal point, the image will always be located somewhere on the opposite side of the mirror. (a) Object distance (u) for a concave or convex mirror is given a negative sign.This is because, the object is always placed to the left of the mirror. A concave mirror has a reflective surface that is curved inward and away from the light source. The size of the image is the same as compared to that of the object. ∴ u < 0. When an object is placed behind the center of curvature, a real image is formed between the center of curvature and focus. In this case, the image will be inverted (i.e., a right side up object results in an upside-down image). when an object is placed at infinity, a real image is formed at the focus. Different types of images are formed when the object is placed: The image formed in a convex mirror is always virtual and erect, whatever be the position of the object. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted.

When you keep an object in front of a concave mirror, an enlarged image of the object is formed when it is kept close to the mirror and an inverted image of the object is formed when it is kept at a distance. Identify the means by which you can use a concave and/or a plane mirror to form a virtual image. It would appear to any observer as though light from the object were diverging from this location. Plane mirrors never produce inverted images. If the cut part of the hollow sphere is painted from inside, then its outer surface becomes the reflecting surface. When the concave mirror is placed very close to the object, a magnified and virtual image is obtained. Distances measured on the other side are negative. The size of the image is smaller than compared to that of the object. Nine different object locations are drawn and labeled with a number; the corresponding image locations are drawn in blue and labeled with the identical number. Concave mirrors reflect light inward to one focal point. Example • An object is placed 6.00 cm in front of a concave mirror that has a 10.0-cm focal length. • (b) The object is 1.2 cm high. From above, it can be observed that image distance v is negative when object is virtual. Hence, it is also known as a converging mirror. These patterns are depicted in the diagram below. Finally, the image is a real image. The famous Chinese magician, Foo Ling Yu, conducts a classic magic trick utilizing a concave mirror with a focal length of 1.6 m. Foo Ling Yu is able to use the mirror in such a manner as to produce an image of a light bulb at the same location and of the same size as the actual light bulb itself. Since, the centre of curvature and focus lies behind the convex mirror, so radius of curvature and focal length are taken as + (positive) in the case of convex mirror. The image produced is: asked Oct 13, 2020 in Physics by Jaanvi01 ( 58.0k points) Earlier in Lesson 2, the term magnification was introduced; the magnification is the ratio of the height of the image to the height of the object. Ray diagrams help us trace the path of the light for the person to view a point on the image of an object. At what distance from the mirror should a screen be placed to obtain a sharp image?
