Defects in Rutherford’s model

Defects in Rutherford’s model Although Rutherford’s experiment proved that the, plum-pudding, model of an atom was not correct, yet it had following defect: 1.    According to classical theory of radiation, electrons being the charged particles should release or emit energy continuously, they should from a continuous the nucleus. 2.    If the electrons emit energy continuously, they should form a continuous spectrum but in fact, line spectrum was observed. Although the scientists had objections on the atomic model...

International system of units

International system of units Measuring is not simply counting. For example, if we need milk or sugar, we must also understand how much quantity of milk or sugar we are talking about. Thus, there is a need of some standard quantities   for measuring\comparing unknown quantities. Once a standard is set for a quantity then it can be expressed in terms of that standard quantity. This standard quantity is called a unit.        With the developments in the field of science and technology, the need for a commonly...
