Single-Wire/Single Slit Diffraction 

Description

This instrument using laser diode as the light source and using a silicon photocell to measure the light intensity distribution of light diffraction, Fraunhofer diffraction phenomenon can be observed by single and single slit and circular aperture, and the influence of wavelength, slit width, diameter change on the diffraction theory of light diffraction, deepen the understanding of the. The product is made of high strength and high quality aluminum alloy. The surface is anodized.

Experiments

1.Observe single-wire/single-slit diffraction

2.Measure diffraction intensity distribution

3.Learn relationship of intensity vs wavelength

4.Realize relationship of intensity vs slit width

5.Understand Heisenberg uncertainty and Babinet’s principles
