Project a Spectrum
Reflecting mirror
Place two black sheets of construction
paper on an overhead projector stage,
forming a 2-cm-wide vertical slit in
the center. Place a piece of diffraction
grating film over the lens of the projector.
Two spectra will be projected
vertically to the left and right of the
beam of white light on the screen. If
spectra are not visible, rotate the diffraction grating 90 degrees.

Light Sticks
All chemicals involved are safe, and the tubes can simply be
discarded
in the trash when exhausted. Each light stick will
remain lit for about 12 hours. Packaged in individual foil wrappers,
the sticks can be stored in this wrapper until ready for
use—up to four years. Each light stick measures 6" long x 5/8" in diameter.

LED Light Blocks
Affordable and effective! Quickly and easily
demonstrate reflection, refraction and color
mixing. Unique design includes adapters that fit
on the end of each block to create a thin light
beam that can be directed through optical blocks
to study reflection, refraction and focal length.
Arrange the beams to be parallel, diffused or convergent. Remove the adapters
to create wider beams of light to show color mixing—blue + green + red = white
light! A magnet is attached to the bottom so these versatile blocks can be used for
classroom demonstrations on a whiteboard. 41/2" x 11/4" x 3/4".

AP7771 LED Light Blocks $32.70
Optics and Light—Diffraction
Diffraction Grating Film See page 438.
Measuring with Laser Light—
Student Laboratory Kit
By: The Flinn Staff
Students use a laser pointer to measure
the width of three objects—fishing line,
copper wire and a strand of human hair. As
the laser light bends around each object,
students analyze the diffraction patterns
produced. Concepts such as wavelength,
diffraction and constructive and destructive
interference become clear. When
students compare the experimental values
with the accepted values, they will be astonished at the accuracy of this “high-tech”
method of measurement! Teacher Notes with sample data, extensive background
information and reproducible student worksheet are provided. Includes six laser
pointers, fishing line, copper wire and materials to make frames for the objects being
measured. Students supply their own hair.
Complete for 24 students working in groups of four.
