Diffraction

- Diffraction Through One Slit (6C10.10) link to file 6c10_10.htm

-Turn on the laser. The pattern appears on the wall.

-The slit widths are printed on the slide.

-To select a different slit, slide the holder sideways.

- Diffraction Around Objects (6C20.10) link to file 6c20_10.htm

-Turn on the laser. The pattern appears on the wall.

-To selects a different object, slide the holder up and down or sideways.

- Interference and Diffraction (3B50.40) link to file 3b50_40.htm

-Pairs of identical transparencies have circular wave patterns of different wave lengths.

-Place transparencies on the overhead projector.

-Vary their relative positions to produce different interference patterns.
