Abstract: The important significance of the path and path difference in course teaching of optics is discussed.  Through analysis and discussion,it is pointed out that the path difference is the main channel for teaching optics.  To address this main channel from the beginning to the end in teaching optics is very important and necessary.

Key words: optics, path, path difference
