• B. $5$
• C. $3$
• D. $4$

Answer 1

Answer: (C)

$3$

Kaleidoscope can be either of $2$ or $3$ mirrors. $3$ mirrors yield a pattern that fills the entire field.

A kaleidoscope is a toy that uses light and mirrors to reflect objects and create beautiful, fascinating repeating patterns. There are many different types of kaleidoscopes that create different patterns, but all use the same basic laws of physics, manipulating light and reflection.

A two-mirror kaleidoscope yields a pattern or patterns isolated against a solid black background, while the three-mirror type yields a pattern that fills the entire field.
