IMO, in the context of magnification, height and width are proportional, so if magnification is 2, then both the height and width are multiplied by 2. I think they only take height in numericals to avoid confusing students. 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.
