Doppler effect (C.J. Doppler)
Waves emitted through a moving object as attained by an observer will be blueshifted (compressed) if approaching, redshifted (elongated) if receding. It takes place both in sound with electromagnetic phenomena, though it takes on different forms in each.
Describe the numerical aperture in the optical fibre. Numerical Aperture: The numerical aperture is described as the sine of the acceptance angle. Therefore, Numerical
Factors affecting capacitance: The factors which affect the capacitance of a parallel-plate capacitor are: Overlapping area of the plates (A). The capacitance increases
Two forces P & 2P act on the particle if the first is doubled & the second enhanced by 20N.The direction of the resultant remains unchanged. What is the value of P.
The thrust developed to propel the jet ski shown in Fig is a result of water pumped through the vehicle and exiting as a high-speed water jet. For the conditions shown in the Fig,
Resistance: Resistance is the opposition to the motion of electrons. This arises as a result of collision of moving electrons. The unit of resistance is "ohm" represented by
Explain the Electromagnetic Induction The force exerted on an electric charge moving in a magnetic field leads to the idea of magnets being able to produce electricity as well
what are solid core fibres?
compare the contributions of faraday and oersted to electromagnetic theory
INSTANTANEOUS ACCELERATION: The acceleration of the body at any certain instant during its motion is called to be an instantaneous acceleration.
