Propagation of electromagnetic waves

Electromagnetic radiations are also known as electromagnetic waves which are basically described as a superimposed oscillation of an electric and magnetic field in space which is perpendicular to each other. In other words, electromagnetic waves are produced due to crossing-over an electric and magnetic field. The direction of these types of waves is perpendicular to … Read more

Need for modulation, amplitude modulation and frequency modulation

Need for modulation A communication channel just works at a specific frequency range like telephone cables, terrestrial (over the air broadcast), ethernet, optical fiber, etc. Modulation deciphers a signal from its baseband to the working range of the channel. By modulating various signals to various frequency bands, they can be transmitted at the same time … Read more

Energy bands in conductors, semiconductors and insulators

Energy Bands in Conductors: Metals like copper, aluminum we can see no forbidden gap between the valence band and conduction band. The two gaps cover. Subsequently, even at room temperature, an enormous number of electrons are accessible for conduction. So with no extra energy, such metals contain an enormous number of free electrons and subsequently … Read more

Energy levels

The energy level in quantum mechanics defined as a system or particle that is bond and confined spatially or which can only take on certain discrete values of energy. This makes a contrast between this and classical particles which can have any amount of energy. In physics, this term is commonly used for the energy … Read more

Hydrogen spectrum

All the lines in the absorption and emission of the spectrum of hydrogen when each one corresponding to an allow transition between the level of quantum energy it has been divided into a number of spectral series with wavelength given and these transitions are been seen between the energy due to the working of an … Read more

Radioactive Decay Law

The law about radioactive decay is a universal law, and it is used for describing the statistical behavior of a large number of nucleoids. The radioactive decay is not a regular process but a random one. It occurs at the level of single atoms, and according to the quantum theory, the prediction about the decay … Read more

Bohr model

Bohr model or Rutherford-Bohr model is a system consisting of a dense nucleus which is surrounded by orbiting electrons it is similar to the structure of the solar system. Though its structure is same like the solar system but it is attracted by electromagnetic force in place of gravity. This model is based on the … Read more

Radioactivity Alpha, Beta and Gamma

Radioactivity Alpha, Beta and Gamma Particles/Rays and Their Properties When the atoms are undergoing radioactivity, then there is the emission of particles like the alpha, beta, and gamma rays. The radioactivity is occurring due to the unstable atoms, which are trying to attain stability. So, when the atoms are unstable, then eventually, they are decaying … Read more

Rutherford’s model of the atom

This experiment is to describe an atom he proposed that an atom is composed of empty space mostly consisting of electrons orbiting in the set around the positively charged nucleus. This comes into the consciousness of everyone after the observations made by Rutherford and those observations are that the major space in an atom is … Read more

Alpha particle scattering material

This experiment is done for finding some conclusions in the world of science and after processing this experiment they found some conclusions, as well as arguments, are also taking place on this particular experiment. They found that most of the alpha particles passed through the coil without suffering and some alpha particles scattered and more … Read more
