Question

If the tube of a kaleidoscope is filled with thick black smoke, the pattern:

• A. will change and will not be observable
• B. will not change and will not be observable
• C. will not change and will be observable
• D. will change and will be observable

Answer 1

The correct option is B will not change and will not be observable

Above diagram show a simple kaleidoscope .

A kaleidoscope is a toy that uses light and mirrors to reflect objects and create beautiful, fascinating repeating patterns.

The pattern depends upon the positioning of the object and the mirrors. So, the pattern will not change because object and mirror positions are fixed. But, as the tube is filled with thick black smoke, no light will come out to the eye piece. So, the pattern will not be observable.
