WebAedenvelvet. 7 months ago. The centre of the reflecting surface of a mirror is called the Pole(P). It lies ON the mirror. This is different from the Centre of curvature(R). Each spherical mirror forms a part of an imaginary circle. The centre of this circle is called Centre of curvature. It DOES NOT lie on the mirror. WebFigure 16.15 shows the meanings of most of the variables we will use for calculations involving curved mirrors. Figure 16.15 Look for the variables, do, d, ho, h, and f in this figure. The basic equation that describes both lenses and mirrors is the lens/mirror equation. 1 f = 1 d i + 1 d o.

WebDetermining if an Image is Real or Virtual. Step 1: Read the problem. Step 2: Take the values given within the problem and insert them into the Thin Lens equation to … WebA lens is a transparent device with two curved surfaces, usually made of glass or plastic, that uses refraction to form an image of an object. Mirrors, which have curved surfaces designed to reflect rays, also form images. A system of lenses and/or mirrors forms an image by gathering rays from an object and then causes them to converge or diverge. WebIn the equation for(f/#) w, m represents the magnification (ratio of image to object height) of the lens.Note that as m approaches zero (as the object approaches infinity), (f/#) w approaches f/#. It is especially important to keep (f/#) w in mind at smaller WDs. For example, an f/2.8, 25mm focal length lens operating with a magnification of 0.5X will … dj jefersito flow
