Measuring with Laser Light - Student Laboratory Kit
How can an object less than a millimeter wide be measured? Students use a key-chain laser pointer to measure the width of three micrometer-size objects—a fishing line, copper wire, and a strand of human hair. As the laser light bends around each obje...
Simulated Double-Slit Interference
Quickly and confidently demonstrate the concept of wave interference. Stack two identical circle patterns together on an overhead projector. Slowly slide one pattern over the other and the interference pattern will clearly develop before your eyes. T...
Holographic Diffraction Grating Film
Diffraction grating film (holographic type). A diffraction grating is a plane surface which contains literally tens of thousands of microscopic lines or grooves. A phenomenon called “diffraction” causes white light to be split or diffracted into its ...
