Measurements and Uncertainties

Objectives

To learn how to use caliper, micrometer and spherometer,
To measure external dimensions (length, volume) of a given regular body,
To determine depth of a given object using a caliper,
To measure the mass of a given object using equal arm balance and digital balance,
To determine the possible errors in the measurements by ruler, calliper and micrometre, and compare their accuracy,
To etermine the density of a regular body of known mass using different measurement techniques,
To determine the radius of curvature of a spherical surface (lens) with a spherometer (indicator).
