摘要

对水中物点的虚像点坐标提出一种比传统教科书中更简单直接的公式化解法———导数法,得到虚像点位置及其随视角变化的轨迹方程.在直角坐标系中作出该轨迹,同时对这些结果予以一定的解读.

关键词: 虚像点; 坐标; 公式; 视角; 轨迹

Abstract

A formulaic solution,i.e.,derivative method,which is more simple and direct than that in the traditional textbook,is put forward for the virtual image coordinates of an object point in water,and the virtual image point and its trajectory equation with the changes of view are obtained. Thus the trajectory is made in the rectangular coordinate system. Meanwhile,a certain amount of interpretations are given to these results.
