How does bubble size affect the sensitivity of the spirit level?
13. How does bubble size affect the sensitivity of the spirit level?
- A smaller bubble has greater sensitivity
- A larger bubble has greater sensitivity
- Both A and B
- None of the above
Answer
The correct answer is: A) A smaller bubble has greater sensitivity
Explanation
A smaller bubble has greater sensitivity. This is because a small bubble will quickly show the response to the slight angular variation, which will make it easier to detect the surface line (whether horizontal or vertical).
