In a continuous band of frequency if any difference occurs between upper and lower frequencies then this is known as bandwidth and measure in hertz, Whereas the transmission is a medium of a material substance consisting of solid, liquid and gas that can propagate energy waves. It can be understood by an example of the … Read more
In a continuous band of frequency if any difference occurs between upper and lower frequencies then this is known as bandwidth and measure in hertz, It may also be referred as passband bandwidth because it is the difference between the upper and the lower cutoff frequencies of baseband bandwidth which applies to a low pass … Read more
The whole distribution of electromagnetic radiation is according to the frequency and wavelength although all electromagnetic spectrum or waves travel at the speed of light mainly in the vacuum they do this at a wide range of frequency, wavelength or photon energies. This spectrum comprises all electromagnetic radiation which also includes subranges which are known … Read more
All the atoms of elements are not identical, and some atoms of the same elements are having a different number of neutrons. The different versions of atoms of the same elements are known as isotopes. Atoms are composed of neutrons, protons, and electrons. The neutrons and protons are present in the nucleus, and electrons are … Read more
Nuclear fission is an important process in nuclear physics, where the atom’s nuclei are splitting into two or more smaller nuclei, as the fission products, and as some by-products usually. Fission is an important form of elemental transmutation. In the byproduct’s electrons, protons, and neutrons are included. It also includes the photons in the form … Read more
Matter waves belong to the family of quantum mechanics as a central part of this family and it is mentioned that all matter can exhibit wave-like behavior as a beam of light or electrons can be detracted just like another beam of water. Another name of matter waves is de Broglie waves and its wavelength … Read more
In simple words, radiation means the emission of energy or it can be said that transmission of the energy in form of waves or particles through a material medium it also includes electromagnetic radiations which are included as radio waves, microwaves, infrared, visible light, and gamma radiation. Radiation consist of two categories including ionizing and … Read more
Einstein’s photoelectric effect- particle nature of light Albert Einstein great scientist in 1905 proposed that light can be called quanta of energy that also behalf as particles. He also explained that photon is a particle of electromagnetic radiation that has zero mass and also carries a quantum of energy. This is tried and tested because … Read more
This observation is related to the photoelectric effect and how this effect is proven by two scientists one experiment was conducted in 1887 by Heinrich Hertz to prove electromagnetic theory of light when he observed strange phenomena as he placed two electrodes at small distance so that an electric spark can be generated and he … Read more
When light hits any material there is an emission of electrons and other free carriers and this whole process is called photoelectric effect and in the manner that electrons were emitted is called photoelectrons. According to many theories, this effect can be concluded from the transfer of energy from light to an electron so from … Read more
