Experiment: Determination of the radius of curvature of a spherical surface by a spherometer. Theory: Radius of the curvature which is the portion of a sphere is called the radius of curvature of the spherical…

Accurate digit in the experimental result Accuracy of a measured quantity depends on the accuracy of the associated quantities related to the measured quantity. But when we use calculator for calculation, we get many digits.…

Random errors: Inspite of taking enough care to avoid different errors measurement of a quantity again and again appears to be different. This type of difference in measurement may occur for two reasons; (i) due…

For the measurement of any physical quantity two types of errors are observed. (I) Systematic errors and (2) Random errors. Here briefly describe on Systematic errors. Systematic errors: While performing experiments due to some errors experimental…

Dimension: We have discussed earlier that according to the origin quantities are of two types-one is fundamental quantity and the other is compound quantity. Also we know that those quantifies which do not depend on…

Principle of Measurements We know, measurement is the process to know a quantity accurately. Without measurement it is not possible to have accurate knowledge about a quantity. Actually, basic principle of physics is to take…

The necessity of Dimensional Equations The importance of dimensional equation in physics is enormous. Its importance’s are discussed below: (1) To find the dimension of constants in a given relation. One form of the unit…
