Answer 1

Explanation:

While calipers are the most typical use of vernier scales today, they were originally developed for angle-measuring instruments such as astronomical quadrants. In some languages, the vernier scale is called a nonius after Portuguese mathematician, cosmographer Pedro Nunes (Latin Petrus Nonius, 1502–1578).

Answer 2

Answer:

A vernier scale is a visual aid to take an accurate measurement reading between two graduation markings on a linear scale by using mechanical interpolation; thereby increasing resolution and reducing measurement uncertainty by using vernier acuity to reduce human estimation error.
