The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. For a standard rectilinear lens, FOV = 2 arctan x / 2f, where x is the diagonal of the film. Find the position of the image. !, because there is no centre of curvature. Posted Example 4: An object is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. 13 hours ago, Posted For a standard rectilinear lens, FOV = 2 arctan x / 2f, where x is the diagonal of the film. Solution: We have u = –15 cm and f = –10 cm Find the position of the image. That is F = infinity. Calculate this using the spherical mirror equation and the fact that do-di 2. Focal length (f) and field of view (FOV) of a lens are inversely proportional. (b) Determine the focal length of the mirror. 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. parallel to the focal axis), it is reflected back by 180* parallel to the focal axis.

Get … 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. 19 hours ago, Posted What is themagnification of a plane mirror? (b) Determine the focal length of the mirror. ?1s mirror is placed 2.0 cm from a tooth. A dentistA??? The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. In a plane mirror, the radius of curvature is infinitly long, so the focus will be at infinity. Best Answer 100% (1 rating) Previous question Next question Get more help from Chegg.

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… No focal length in plane mirror,because there is no center of curvature in plane mirror. The enlarged image is located 5.6 cm behind the mirror. The enlarged image is located 5.6 cm behind the mirror. 1. It can be said that these parallel rays will converge at infinity. This can be shown as follows... when a ray of light falls on the mirror perpendicularly (i.e. 0 1. Two plane mirrors are located parallel to each other and are separated by 90.0 cm as shown in figure 1.

There is no focal length for a plane mirrior!!!! 16 hours ago, Posted Pinky A. samriddhiyadav717 is waiting for your help. A dentistA??? 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… (a) What is the focal length of a plane mirror? Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror =$$\frac { 30 cm }{ 2 }$$ = 15 cm. Solution: We have u = … (a) What kind of mirror (plane, concave, or convex) is being used? ?1s mirror is placed 2.0 cm from a tooth.
