Dec 1, 2023 · The image formed by the concave mirror becomes the virtual object for the plane mirror, and the image formed by the plane mirror will be at the same distance behind the mirror as the virtual object is in front of it. So, the final position of the image is twice the distance calculated for \( v \) with the concave mirror formula.
Generally the convex mirror has magnification greater than 1 and magnification of concave mirror has less than 1. With magnification greater than 1, as the image size is greater than object size. And with magnifications less than 1, image size is less than one. In case of plane mirror, the image size produced is same as that object size.
Sep 22, 2020 · 1. in plane mirror image is erect. 2. the image formed by plane mirror is virtual.
May 8, 2020 · For a plane mirror, focal length is infinity. Hence, putting thee value of f in above formula, 0=1/u+1/v. 1/v=-1/u. v=u. Here, the object distance becomes equal to image distance which proves mirror formula can be applied to a plane mirror. A reason is true only if the plane mirror is of infinite radius of curvature and the focal length i.e R=f ...
A plane mirror is just a flat piece of glass or metal that has been coated with a thin layer of metal, typically aluminum or silver, which allows it to reflect light. When light from our face strikes the surface of the mirror, it bounces back to our eyes in a way that allows us to see a clear image of our face.
Apr 13, 2017 · If a plane mirror is approaching to you with the speed of 10cm/s then at 1st second the distance b/w object and mirror will be 10, so the distance b/w object and image will be 2*10=20 b'coz in plane distance b/w object to mirror is same to the distance from image to mirror. So the image will be approaching with the speed of 20cm/s.
Dec 14, 2016 · ''when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence''. So, the angle of incidence = angle of reflection. Hence, the angle of reflection is 55°.
Feb 8, 2021 · An image formed by a plane mirror has the following characteristics: A virtual picture is always formed by a plane mirror (behind the mirror). It is erect and of equal size to the object. The object's distance from the plane mirror is the same as the image's distance from the plane mirror.

Jan 19, 2018 · X is the mirror and R is a point on the screen. Distance of laser point from X = 8cm. To find: Distance of point of incidence from X Calculation: From the figure below: MN is the normal at the point of incidence i.e. O. Let the angle of incidence be x, then the angle of reflection will also be equal to x. From ΔAXO and ΔRBO: ∠AXO = ∠RBO ...
