power of gamma rays

They are not deflected by electric and magnetic fields. They affect photographic plates. The ionising power is very low compared to alpha-particles and beta-particles. They are electromagnetic waves like X-rays and light rays. The wavelength of these ra..

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

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..

Whenever a ray of light passes through a lens (except when it passes through the optical center) it bends. The bending of light rays towards the principal axis is called convergence and bending of light rays away from the principal axis is called divergence. The degre..

X-Rays follow a rectilinear propagation and travel with a velocity of 3 x 10 8 ms - 1 in vacuum. They are not deflected by electric and magnetic field. Since they do not contain any charge but are diffracted by crystals, X-rays cause fluorescence when incident on certain mate..

The magnifying power or angular magnification of a microscope may be defined as the ratio of the angle subtended at the eye by the image formed at the distance of the distinct vision to the angle subtended by the object when placed at the distance of the distinct vision. The ray..

(i) b - rays consist of negatively charged particles and have the same mass as that of an electron. (ii) Since their velocities are 1/10 t h of the speed of light they are considered as fast moving electrons. (iii) The penetrating power of b -particles is larger than that ..

Beta rays are made up of streams of negatively charged particles similar to electrons. Thus, - particle has a unit negative charge and a negligible mass. They are electrons. Hence, - particle is represented as -1 e 0 . They affect photographic plate. They get deflected to the..
