beta and gamma rays

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..

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

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..

They get deflected by electric and magnetic fields. The deflection is large since a beta particle is lighter than an a -particle. They affect photographic plates. They ionise the gas through which they pass. The mass is 9.1 x 10 - 3 1 kg and its charge is 1.6x10 - 1 9 C...

If α > β > γ are any three real numbers, then the points A ( α , β + γ), B ( β , γ + α ) and C (γ, α + β ) are => The vertices of a right isoscel..

If α , β are the roots of x 2 - 3 x + a = 0 and γ, δ are the roots of x 2 - 12 x + b = 0 and the numbers α , β , γ and δ (in order) form an increasing G.P then ________ => a = 2, b = 8 or a = 2, b = 32 or a = 2, b..

The displacement function of a particle with time t is given by S = 4 α cos(4 β t + γ) where α , β , γ are constants. If V and f are the velocity and acceleration of the particle respectively at time t , then d f d S = ? => -..

The rays that deflected towards the negative plate consist of positively charged particles and these were called alpha rays. The rays, which deflected towards the positive plate, consist of negatively charged particles and these rays were known as the ..

Radioactivity - It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur due to any external provocation ..
