Mirrors and Lenses in Optical Devices

To observe over, around, or through an obstacle or condition that prevents direct line of sight observation.

It consists of an outer case with mirrors at each end set parallel to each other at a 45 degree angle.

To reflect objects and create beautiful, fascinating repeating patterns.

<p>Light filters through the glass on the end of the object chamber and illuminates the objects, which then reflect off all the mirrors.</p> Signup and view all the answers

<p>A periscope is used for observation over, around, or through obstacles by employing mirrors set at a 45-degree angle. An example is its use by submarines to search visually for nearby targets and threats when submerged.</p> Signup and view all the answers

<p>A kaleidoscope uses light and mirrors to reflect objects, creating beautiful repeating patterns. The patterns are formed as the reflections bounce off each other inside the kaleidoscope.</p> Signup and view all the answers

<p>The basic laws of physics manipulated in a kaleidoscope are related to light and reflection, as the light filters through the glass, illuminates the objects, and their reflections bounce off multiple mirrors to create the patterns.</p> Signup and view all the answers
