PASCO SE-9361 DIFFRACTION GRATING - Manual

IMPORTANT: To avoid scratching or soiling the surfaces of the
gratings, hold the slide only by its edges.

DIFFRACTION GRATING
(Set of Four)
Introduction
The PASCO Diffraction Gratings (set of four) have line spacings of 80, 100,
300, and 600 lines/mm. They are excellent for quantitatively studying the
relation between line spacing, angle of diffraction, and wavelength. Each grating
is covered with glass on both sides.
Suggested Uses
1. Look at various light sources through the gratings and examine the spectra.
Which colors of light are diffracted to the greatest angles? How does the
shape and orientation of the light source effect the pattern?
2. Using a line-filament light source, compare the diffraction patterns pro-
duced by the gratings. How does the angle of diffraction vary with the line
spacing of the grating?
3. Examine the spectra of various spectral light sources. Show your students
how an element can be "fingerprinted", allowing scientists to analyze the
composition of unknown materials, and even to determine the composition
of stars.
