experiment 1 (9th and 10th)how to draw vernier caliper how to do experiment 1 varnier caliper and how to work of prctical Experiment 1 Measurement Object To study the vernier scale principle and to learn the use of vernier calipers for the accurate measurement of length. To become familiar with the use of micrometer calipers for the accurate measurement of small lengths Theory Careful quantitative measurements are very important for development of physics, the most exact of the experimental sciences. The measurement of length is basic to many of the experiments performed by physicists. Measurement with rulers a) The use of an ordinary ruler, such as a meter ruler, is a simple way of measuring length. b) Readings on this scale should be made to fractions of a millimeter c) Start at 1 cm, not 0 cm. Fig.1.Ruler 1. The Vernier Principle: a) For small divisions on a scale, a vernier scale, invented by Pierre Vernier in 1631, can be used to measure the fractional parts more ...
