Measuring with Laser Light—Student Laboratory Kit Manufacturer,Supplier and Exporter in India
Product Code : EL-MD-11225
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 object, students analyze the diffraction patterns produced.
When students compare the experimental values with the accepted values, they will be astonished at the accuracy of this “high-tech” method of measurement!
Concepts such as wavelength, diffraction, and constructive and destructive interference become clear as students calculate the width of each object.
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.
Complete for a class of 24 students working in groups of four.
Students supply their own hair.
