Exploring concave mirror images the pdf file below accompanies the concave mirror image formation interactive. The purpose of this lab is to introduce students to some of the properties of thin lenses and mirrors. Have you ever gone camping in the night or have walked inside a cave. Used to focus light, they reflect it inward toward one focal point. In case of convex mirror, parallel rays are diverged.
Images formed by spherical mirrors can be analyzed by. As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror. An image formed by a concave mirror, based on an objects distance from the mirror and the mirrors focal length skills practiced this quiz and worksheet allow students to test the following skills. A curved mirror formed by a part of a hollow glass sphere with a reflecting surface created by depositing silver metal is also referred to as a spherical mirror. Curved mirrors are also used, to produce magnified or diminished images or focus light or simply distort the reflected. The primary goals are to understand the relationship between image distance, object distance, and image scale. Convex mirrors center of curvature and focal point both located behind mirror the image for a convex mirror is always virtual and upright compared to the object a convex mirror will reflect a set of parallel rays in all directions.
This one factor allows a very large usage of convex mirrors. Drawing concave mirror ray diagrams in optics with a real image part 1. An image or an array of images may be formed due to this. Therefore, it covers are a larger field of view compared to a plane or concave mirror. A curved mirror is a mirror with a curved reflecting surface. Nature of image formed by convex lens and concave lens. When parallel rays could be from a distant object incident on a concave mirror, the reflected rays converge to a focal point f, hence also called converging mirror. Nature of images in a convex mirror and its applications. If a virtual image is formed along the principal axis 10. Formation of image by a concave mirror in ray diagram. Lets start drawing images of the objects located in different parts of the mirror.
A convex lens of focal length 6cm is held 4cm from a newspaper, which has print. Simple explanation for rules for image formation for curved mirrors. Explain formation of different types of images by a concave mirror with the help of diagrams. Different types of images can be formed by a concave mirror by changing the position of the object from the concave mirror. This is because the rays of light falling parallel once reflected diverge. A rectangular block of glass is placed on a printed page laying on a horizontal surface. Each mirror has a radius of curvature r which is in. Image formation by concave mirrors richard fitzpatrick. Compared to other reflective mirrors, the field of view for a convex mirror is the maximum. Curved mirrors may produce images of various different natures. When an object is placed opposite to a concave mirror. Diffused light allows you to read a printed page from almost any. A mirror is an object that reflects light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original. In a concave mirror, the size of real image will increase, only.
If the object placed at the center of the mirror, image is also formed at center, real, inverted and with the same size as object. Various terms associated with spherical mirrors spherical mirror. Explain reflection from mirrors, describe image formation as a. The type of image formed by a concave mirror depends on the position of. Where an object should be placed in front of the concave mirror so as to obtain a. The physics classroom grants teachers and other users the right to print this pdf document and to download this pdf document for private use. There are two alternative methods of locating the image formed by a concave mirror. Therefore different types of images are formed when the object is placed 1. These images are also termed virtual images because when they occur. Rules for image formation in concave and convex mirrors. Images formed with convex mirrors are always right side up and reduced in size. In general, the image formed by a convex mirror is upright, virtual, and smaller.
