Answer 1

Another difference

Kaleidoscope- There are usually three mirrors each at 60 degrees forming an equilateral triangle.

Answer 2

Differences - Periscope and Kaleidoscope

The periscope is a device for observation. It helps to observe a given object if the object can not be seen through direct sight with line of sight.  Kaleidoscope is also an optical device which is used for observing the repeated form of reflection of a given object.  

The differences between them are as follows -

1. The periscope has two mirrors in its instrumentation while the kaleidoscope has three.

2. The mirrors in periscope are inclined at an angle of 45 degrees in periscope whereas inclined at 60 degrees in kaleidoscope.

3. The periscope is used to observe what is not seen through direct line of sight whereas kaleidoscope forms repeated reflective image to produce beautiful patterns.

4. The periscope produces the visibility of minimum range where as the kaleidoscope represent symmetrical pattern with high visibility.
