A vernier scale improves the precision of a measurement. Let us compare a standard meter stick to the Vernier calipers used in this lab. Each of these instruments has a least count of 1mm.
a) For a meter stick, what would you be comfortable using as the smallst estimated fraction of the least count? What fraction of the least count is this?
b) For the Vernier calipers, what is the smallest estimated fraction of the least count according to your manual? What fraction of the least count is this?
c) By at least what factor does using Vernier calipers improve your precision(compare the fractions of the least count from a) and b)?
