Optical instruments made by students

In the topic, Basic of light, I give the task of analyzing and creating one simple optical instrument for themselves. Students have two weeks to prepare projects, returning to these issues.

Assignment given to students: 
Select one device that uses light straight-line travel or light reflections and studies it!

• What, when, and for what purposes did create the first model of this device?
• What is the physical principle of the operation of the device?
• What are the options for using the device these days?
• What other technical solutions use the principles of this device?
• Create a technical plan to make a model for such a device!
• Create a device and evaluate the outcome of your work

Here are some of bests for this year!
