PASCO OS-8529 SLIT ACCESSORY - Manual (Page 12)

Slit Accessory 012–06348A
Procedure
➀ Follow the setup procedure on page 2 of the manual using the
Multiple Slit Set with the single-double slit comparison selected.
➁ Sketch the two side-by-side patterns roughly to scale.
➂ Rotate the slit disk to the next comparison set (2 double slits with
the same slit width but different slit separations). Sketch the two
side-by-side patterns roughly to scale.
➃ Rotate the slit disk to the next comparison set (2 double slits with
the same slit separation but different slit widths). Sketch the two
side-by-side patterns roughly to scale.
➄ Rotate the slit disk to the next comparison set (double slits/triple
slits with the same slit separation and same slit widths). Sketch the
two side-by-side patterns roughly to scale.
➅ Replace the Multiple Slit Set with the Single Slit Set. Select the
line/slit comparison. Sketch the two side-by-side patterns roughly
to scale.
➆ Select the dot pattern, and sketch the resulting diffraction pattern
roughly to scale.
➇ Select the hole pattern, and sketch the resulting diffraction pattern
roughly to scale.
Questions
➀ What are the similarities and differences between the single slit
and the double slit?
➁
How does the double slit pattern change when the slit
separation is increased?
➂ How does the double slit pattern change when the slit width is
increased?
➃ What differences are there between a double slit pattern and a
triple slit pattern?
