gamma rays wavelengths

Gamma decay is the phenomenon of emission of gamma ray photon from a radioactive nucleus...

Emission of a and b -rays bring some changes in the nucleus of the atom and the new element formed as a result of these charges is called daughter elemen..

In 1899, the study of radioactivity was taken up by Ernest Rutherford. He placed a little radium at the bottom of a small lead box and subjected the rays that emerged from it to the action of a very strong magnetic field at right angles to their direction. He found that the rays..

De-Broglie Wavelength of an Electron - Similar to the crystal diffraction patterns produced by X-rays, even the beam of electrons of appropriate momentum could produce crystal diffraction pattern. Imparting the desired momentum to the electron obtained by thermionic emission fro..

They travel in straight lines. They remain undisturbed in an electric as well as magnetic field. They can pass through opaque objects such as black paper. They can affect a photographic plate. They are, in fact, electromagnetic waves of very short wavelength..

.e., CD line, then it is evident that as compared to the ray Y, ray Z has to travel a longer distance, equal to QRS in order to emerge out of the crystal. If the waves Y and Z are in phase after reflection, the difference in distance travelled by the two rays must be e..

The different types of electromagnetic radiations in the increasing order of wavelengths are, gamma rays ( g ), X-rays, ultra-violet rays (U.V.), visible radiation, infrared radiation (IR), microwaves and radio wave..

. It is abbreviated Z. Mass number is defined as the sum of the number of protons and neutrons in the nucleus of the atom. It is denoted by 'A'. Atoms of the same element having same atomic number but different mass numbers are called isotopes. Isotopes show similar chemical properties but the phys..

Glass allows the heat rays of shorter wavelength to pass through it but does not allow the heat rays of larger wavelength to escape from it and thus it is able to trap heat inside a containe..

Beta particles deviate more than alpha particles showing that beta particles are lighter than alpha particles or vice versa. Gamma rays do not deviate as they are electromagnetic waves and hence have no charge..
