The enlarged image is located 5.6 cm behind the mirror. Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror =$$\frac { 30 cm }{ 2 }$$ = 15 cm. What is the focal length of a plane mirror? Solution: We have u = … 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… The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. 23 hours ago. Focal length of a plane mirror is infinite. Focal length is half of radius of curvature and hence it is infinity. (b) Determine the focal length of the mirror. Two plane mirrors are located parallel to each other and are separated by 90.0 cm as shown in figure 1. You can use the mirror formula also to get the focal length of a plane mirror, where the image distance = − object distance. 20 hours ago, Posted A dentistA??? Find the position of the image. 19 hours ago, Posted Calculate this using the spherical mirror equation and the fact that do-di 2. For a standard rectilinear lens, FOV = 2 arctan x / 2f, where x is the diagonal of the film. …. ?1s mirror is placed 2.0 cm from a tooth. 13 hours ago, Posted (a) What is the focal length of a plane mirror? Add your answer and earn points. 6 years ago, Posted 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… 1/F = 1/U - 1/U = 0. 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. 0 0. What is themagnification of a plane mirror? 1. The enlarged image is located 5.6 cm behind the mirror. 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. The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. Get … one year ago, Posted Anonymous. That is F = infinity. samriddhiyadav717 is waiting for your help. yesterday, Posted In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity.

Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror =$$\frac { 30 cm }{ 2 }$$ = 15 cm. 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. 4 years ago, Posted This site is using cookies under cookie policy. A plane mirror can be considered as a spherical mirror of infinite radius of curvature. This can be shown as follows... when a ray of light falls on the mirror perpendicularly (i.e. Find the position of the image. No focal length in plane mirror,because there is no center of curvature in plane mirror.
