basic measurement and uncertainty in measurement

Uncertainty in Measurement - When dealing with objects that can be counted, one can always get an exact answer. But while measuring the weight of a person, the volume of milk in a container, the length of a cloth etc. it is not possible to measure them exactl..

All moving objects in our daily life have well defined paths or trajectories. The path or trajectory of an object can be determined by knowing its position and velocity at various intervals of time. However, Werner Heisenberg, in 1927, pointed out that we can never measure accuratel..

Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementary working of these things, the stu..

To determine the position of an object, we must be able to see the object. This can be done with the help of light of suitable wavelength. When a beam of light falls on an object, the photons of this incident light are scattered by the object and the reflected light enters our eye. Now, if the obje..

It should be borne in mind that the uncertainty is not due to lack of sufficiently refined techniques but it is due to the fact that one cannot observe microscopic things without disturbing them. No instrument can observe the position of an electron without affecting its motion. In ..
