• Resumen

  • We have demonstrated both interference and diffraction of a pseudo-double slit using two glass plates with a width and a length of about 5 cm and a thickness of about 5 mm. The plates are attached at the upper and lower ends with Scotch tape of about 0.1 to 0.3 mm between the plates. By adjusting the angle between the two plates, we are able to demonstrate a single-slit diffraction pattern or a double-slit interference pattern. Also we can simulate a changing separation between slits by changing the angle between the plates.
