Resonance
When the frequency of driving force become equal to the natural frequency of an oscillating system, the driving force provides maximum energy and the oscillating system begins vibrating with maximum amplitude. This phenomenon is called as Resonance.
Beats: The periodic vibrations in intensity or loudness of sound because of superposition of two sound waves of similar amplitude and slightly different frequencies are known a
A light is evaluated by a rotating Nicol showed no variation of intensity. Determine the state of polarization?
why the light vibrating in the plane ofincidence is not reflected at Brewster''s angle?
Field Lines A field line is a locus in which is described through a vector field and a beginning location within the field. Field lines are meaningful for visualizing vector f
When the wavelength of wave remains unchanged, the scattering is known as elastic.

Q. Define critical temperature. The temperature at that electrical resistivity of the material suddenly drops to zero and the material changes from normal conductor to a super
Watt; W (after J. Watt, 1736-1819): The derived SI unit of power, explained as a power of 1 J acting onto a period of 1 s; thus it has units of J/s.
The nuclei have been separated on the basis of the number of protons (atomic number) or the total number of nucleons (mass number) as given below: (i) Isotopes: The atoms of ele
The free surface of a liquid always has a tendency to contract and possess minimum surface area. If we want to enhance the surface area of the liquid, work has to be done. This wor
