Vernier Calliper - The meter scale enables us to measure the length to the nearest millimeter only. Engineers and scientists need to measure much smaller distances accurately. For this a special type of scale called Vernier scale is used. Vernier Calliper The Vernier scale consi..

The accuracy of a measuring instrument depends upon the least count of the measuring instrument. For example, length of a body that can be measured using a tailor's tape, cannot be beyond the minimum and maximum length of the measuring tape. Least count of this tape is the least distance that can ..

It is the shortest distance between two ends of the body. For measuring lengths, two methods can be employed, namely direct method and indirect method. Direct methods are employed for measuring small lengths by comparing such lengths or distances with an approved standard of length viz. verni..

Significant Figures and Measuring Instruments - Let us consider the following entries in a Students' Journal: (a) Weight of a calorimeter = 42 g (measuring instrument used is spring balance) The smallest reading the spring balance can record is 1g. There are 42 of 1 g units of measurement. Hence, t..

> (c) up to 4 significant figures - 8.578 Example 3: Suppose you are measuring the diameter of a cylinder using a vernier calliper as 2.38 cm. The accurate value may lie between 2.375 cm and 2.385 cm. In this case figures 2 and 3 are absolutely correct while 8 is reasonably correct. This ..

>Using a slide calliper, the diameter of the pipe and hence, the end correction can be calculated. However, it can also be eliminated by finding the second resonating length as follows: The tuning fork is excited and held over the open end the tube again. The tube is raised further, till ..
