Chandrasekhar limit (S. Chandrasekhar; 1930)
This is a limit that mandates that no white dwarf (a collapsed, degenerate star) may be more massive than approximates 1.4 masses solar. Any degenerate mass more massive has to collapse inevitably into a neutron star.
Biasing Network and Resistor RG Biasing Network (Rs and Cs): JFET is self-biased by using the biasing network R s -C s . Desired bias voltage is obtained when d.c.
why two alpha particles are not released simultaneously in a radioactive decay???
Superconductivity The phenomena from which, at sufficiently low temperatures, a conductor can conduct charge along with zero resistance. The current theory for describing supe
What are single ends? The extreme fiber optics conductor is farthest from the illuminator. The bit which emits light or the end that lights up.
(i) A matter pulse is not electromagnetic in behavior. (ii) Practical observation of matter waves is possible only when the de-Broglie wavelength is of the order of the size of
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.
Containers from used electric bulbs Used electric light bulbs can be made into containers that will substitute for flasks, beakers, test tubes and same devices. With reasonable
What do you understand by half period zones? What is their other name? Distinguish between physical and geometric (wave) approximations of light.
Young's experiment; double-slit experiment (T. Young; 1801): A popular experiment which illustrates the wave nature of light (and indeed of other particles). Light is passed f
as flux = E.A and flux density is equal to flux/A then why A/A cannot e cancelled ?
