of diffraction screens. According to the terahertz wave diffraction characteristics，the width variation of the
diffraction screen is divided into three stages. The optical path variation and intensity distribution of the terahertz
wave are reflected by the time delay and peak amplitude parameters of the terahertz time-domain spectrum. The experiment
can be used as an extension of the knowledge of diffraction in light in class and as an example of the combination
of diffraction theory and practice in physics teaching.
Key words： terahertz wave; straight edge diffraction; optical path; intensity
