Diffraction & Interference

Diffraction & Interference of Light Experiment Set LE-Y (LED Type)


[Product Description]

Young’s Experiment Set (LED Emission Type)

[Overall Advantages to Users]

  • Suitable for the experiments of light interference and diffraction using three-color high-brightness LED as the light source.
  • High flexibility and portability because the set is a combination of 1) Slide holders, 2) Light Diffraction Grating Slide (D20-1842-W1) and 3) High-brightness LED light source (Red, Yellow, Green, Blue), and optical bench is no longer needed.


  • Light interference and diffraction
  • Young’s experiment
  • High-brightness LED light source

[To all users]

  • Young’s experiment with single and double slit became simple and easily.
  • Possible to carry Young’s experiment safely because of the LED light source unharmful to human eyes.

[To teachers]

  • Unlike laser pointers, no worry to damage students’ eyes due to the light source.

[To students]

  • Easy set up even by students themselves either by putting a single light source, or, piling up multiple ones to compare difference in the width of interference bands. In either case, the light source is self-standing vertically on lab-bench.
  • Students themselves can safely/actually observe the spots of interference fringe when looking into them over the slit of the light diffraction grating slide.
