Rye Neck High School Students Apply Geometry To Holograms

MAMARONECK, N.Y. -- Rye Neck High School students in Joseph Perlman’s ninth-grade accelerated geometry classes recently designed and successfully created holograms.

The students have been studying about the properties of trapezoids and exploring how to create projections using different angles; they applied this knowledge into making the holograms.

The students have been studying about the properties of trapezoids and exploring how to create projections using different angles; they applied this knowledge into making the holograms.

For their projects, the ninth-graders used transparency paper, which they cut into four trapezoid pieces and taped together, to create a holographic projector before placing it directly on top of an iPad, according to a release from the Rye Neck Union Free School District. As a result, the virtual image on the device was projected into their classroom, the release said.

“The purpose was to give the students a practical application of the topic,” Perlman said. “They were able to understand how these shapes are crucial to everyday technologies and why certain sizes work better than others.”

As a conclusion to their studies, the students were challenged to build a holographic projector that would create a bigger, clearer image and replicate it onto a larger scale.
