The Light intensity distribution of the Single-slit diffraction and

the Seam width determination

Abstract: The main purpose of the experiment is to observe the single slit Fraunhofer diffraction

phenomena and single slit width with change rules, deepen the understanding of light diffraction theory. Learning light intensity distribution of photoelectric measuring method. Diffraction pattern determine the width of the single slot.

Key words: Single-slit diffraction?Light intensity distribution?photo-current?the seam width
