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 Vern..

AB and CD are two mirrors fixed, as in the diagram, parallel to each other and facing each other, i.e., the reflection on CD is seen on AB. A small telescope and a vernier travelling over a scale, graduated in degrees, constitute the sextan..

Consider an example. A person was asked to measure the thickness of a coin. He recorded the following readings: (i) 0.2 cm with ruler (ii) 0.23 cm with vernier (iii) 0.231 cm with micrometer The accuracy of thickness of the coin depended on the instrument used for measuring the thickness..

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. ..

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..

To Determine the Height of an Accessible Tree using a Sextant - AB and CD are two mirrors fixed, as in the diagram, parallel to each other and facing each other, i.e., the reflection on CD is seen on AB. A small telescope and a vernier travelling over a scale, graduated in degrees, consti..

> (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 ..
