I don't know if that's correct or not. Technically, yes - you could call the focal length of a plane mirror "undefined", since it doesn't have a particular value. What is the contribution of candido bartolome to gymnastics? Focal length is half of radius of curvature of the mirror. Management. What is the reflection of the story the mats by francisco arcellana? Another way to say it is that a plane mirror has no curvature, and as curvature becomes increasingly small, focal length becomes increasingly long.

I... Q: Find the most probable radial position of an electron in the 3d state of the hydrogen atom. This can be shown as follows... when a ray of light falls on the mirror perpendicularly (i.e. For a plane mirror, or perfectly flat mirror, two rays of light shining off just never intersect. Find answers to questions asked by student like you. The expression for the inductance of the inductor is, The velocity of the car is 5.10 ms-1. These are the most widely used mirrors. Why don't libraries smell like bookstores? Plane mirrors – The images formed from a plane mirrors are the reflected images in their normal proportions but reversed from left to right. Median response time is 34 minutes and may be longer for new subjects. ... A: We’ll answer the first question since the exact one wasn’t specified. Focal length. Copyright © 2020 Multiply Media, LLC. But the use of infinity for the value comes from the equation for the focal length of a mirror, f = -R/2, where R is the radius of curvature of the mirror. parallel to the focal axis), it is reflected back by 180* parallel to the focal axis. The reason why a plane mirror has an infinite focal length is that the plane mirror can be considered as a spherical mirror with infinite radius of curvature. I thought a plane mirror has an infinite focal length because it can display an image from as far as the image is while concave/convex objects can only display perfect images (at least clear) when their rays meet at a point. Business. the focus will be at infinity. It can be said that these parallel rays will converge at infinity. A positive number indicates that it is a concave mirror. menu.
