“magnification”的概念、定义、习题解题方法及翻译-物理辞典

单词	magnification
释义	magnification A measure of the extent to which an optical system enlarges or reduces an image. The linear magnification , m, is the ratio of the image height to the object height. If this ratio is greater than one the system is enlarging, if it is less than one, it is reducing. The angular magnification , M or γ, is the ratio of the angles formed by the final image and the object (when viewed directly, in the most favourable position available) at the eye. This is also sometimes called the magnifying power of an optical system
