How are side bands produced ?

Quest Academy replied | 10/05/2016

Side bands are produced by the method of amplitude modulation. It produces two new frequencies (fc + fm) and (fc – fm) around original frequency (fc), which are called side band frequencies.
Upper side band frequency = USB = fc + fm
and Lower side band frequency = LSB = fc – fm.

U.k. replied | 11/05/2016

A sideband is a band of frequencies higher than or lower than the carrier frequency which contain power as a result of the modulation process. All forms of modulation produce sidebands.
he signal components above the carrier frequency constitute the upper sideband (USB), and those below the carrier frequency constitute the lower sideband (LSB).

Find an expression for intensity of transmitted light when a polaroid sheet is rotated between two crossed polaroids. In which position of the polaroid sheet will the transmitted intensity be maximum ?

Shivaji replied | 09/06/2016

The plane-polarised light is the light in which the vibrations of the electric vector occurring in a
plane perpendicular to direction of propagation of light are confined to a single direction in the plane .
Let intensity of light after passing through polarizer P1 is I0 , then intensity of light I1 after passing
through P2, according to Malus law

In an AC circuit in which the applied voltage signal is continually changing from a positive to a negative polarity at a rate determined by the frequency of the supply, as in the case of a sine wave voltage, for example, the capacitor is either being charged or discharged on a continuous basis at a rate determined by the supply frequency.
As the capacitor charges or discharges, a current flows through it which is restricted by the internal resistance of the capacitor. This internal resistance is commonly known as Capacitive Reactance.
it is inversely proportional to the angular frequency and the capacitance and is due to the presence of capacitance in an alternating-current circuit.

its S.I. unit is in Ohms. «less

Jayasimha replied | 09/05/2016

ZERO because dipole has equal and opposite charges thus net charge is 0 and hence flux is also ZERO

Quest Academy replied | 10/05/2016

Net flux enclosed = 0 because net charge enclosed by cube = 0.
