Diffraction by Various Patterns

Diffraction of red and green light by various patterns on a diffraction plate is shown.

The diffraction patterns of red and green light passing through two 0.04 mm crossed slits (pattern H on the diffraction plate) is shown.

The diffraction patterns of red and green light passing through a random array of 225 0.06 mm diameter circular apertures (pattern I on the diffraction plate) is shown.

The diffraction patterns of red and green light passing through a 15X15 array of 0.06 mm diameter circular apertures (pattern J on the diffraction plate) is shown.
