-Instrument Introduction

This instrument uses a movable reading photodetector to measure the intensity distribution of light diffraction, and the focus of the semiconductor laser can be freely adjusted.

-Experimental content

1. Observe the diffraction phenomena of single filaments and single slits, and measure their light intensity distribution

2. Verify the relationship between wavelength, slit width, and light intensity

3. Understand Heisenberg's uncertainty principle

4. Verify the Babinet principle
