(a) What kind of mirror (plane, concave, or convex) is being used? The enlarged image is located 5.6 cm behind the mirror. What is the focal length of a plane mirror? In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity. The enlarged image is located 5.6 cm behind the mirror. For a standard rectilinear lens, FOV = 2 arctan x / 2f, where x is the diagonal of the film. Calculate this using the spherical mirror equation and the fact that do-di 2. It can be said that these parallel rays will converge at infinity. What is the magnification of a plane mirror? The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. Focal length is half of radius of curvature and hence it is infinity. Find the position of the image. Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror =$$\frac { 30 cm }{ 2 }$$ = 15 cm.

Get … What is themagnification of a plane mirror? ?1s mirror is placed 2.0 cm from a tooth. © 2007-2020 Transweb Global Inc. All rights reserved. This can be shown as follows... when a ray of light falls on the mirror perpendicularly (i.e. (a) What kind of mirror (plane, concave, or convex) is being used? No focal length in plane mirror,because there is no center of curvature in plane mirror. 20 hours ago, Posted That is F = infinity. Solution: We have u = … Add your answer and earn points. Focal length (f) and field of view (FOV) of a lens are inversely proportional. Source(s): My sources are my science textbooks!!!!!. A dentistA??? This site is using cookies under cookie policy. 1. A plane mirror can be considered as a spherical mirror of infinite radius of curvature. !, because there is no centre of curvature. You can use the mirror formula also to get the focal length of a plane mirror, where the image distance = − object distance. (b) Determine the focal length of the mirror. Focal length of a plane mirror is infinite. Example 4: An object is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. 0 0. 16 hours ago, Posted 19 hours ago, Posted What is the focal length of a plane mirror? I know that the focal lengthof a plane mirror is infinite, but I need help with themagnification. Solution: We have u = –15 cm and f = –10 cm parallel to the focal axis), it is reflected back by 180* parallel to the focal axis. 4 years ago, Posted Find the position of the image. 1 decade ago. 23 hours ago. 0 1. When a photographic lens is set to "infinity", its rear nodal point is separated from the sensor or film, at the focal plane, by the lens's focal length… Example 4: An object is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity. ius of the hole if both of the spirit and the plate are kept at the same temperature how much heat must be put into the two so that the ball just passes through the hole.

There is no focal length for a plane mirrior!!!! ?1s mirror is placed 2.0 cm from a tooth. 6 years ago, Posted A plane mirror is considered as the limit of either a concave or a convex spherical curved mirror as the radius & so the focal length becomes infinite. Two plane mirrors are located parallel to each other and are separated by 90.0 cm as shown in figure 1. When an object is placed infront of a plane-mirror an image is formed behind the mirror at a distance equal to the distance of the object from the mirror.That is distance of the image from the mirror= V = -U. from the law of distances, 1/F = 1/U + 1/V.
