A wave front is a line or surface on which the disturbance has the similar phase at every position. If the source is periodic, it generates a succession of ray front, each of the same shape. Ripples on a pond are the example of wave fronts.
sir in books like hc verma i have seen if centre of mass remains at rest... then mx = mX...how?
A parallel plate capacitor has plates of area 200 cm 2 and separation among the plates 1.00 mm. What potential difference will be manufactured if the charge of 1 nC is given to th
How is transmitter used in fibre optic communication system? Transmitter: This consists of analog to digital interface (driver). There, the input signal is converted within
Physical arrangement of resistors: Before we look at some problems it is necessary to warn you that physical appearances can be deceptive. When components are mounted they are
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
What is the Specific Heat of Copper? Ans) 387 J/Kg. C or 0.0924 Cal/g.C
If either screen or source or both are at preset distance from the diffracting device (obstacle or aperture), the diffraction is known as Fresnel type.
Laws of limiting friction
Capacitors in parallel: Three capacitors are connected in parallel. If on closing the switch S a current I flows in the circuit, then from Kirchoff's first law:
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
