Law of Radioactive Disintegration

The rate of radioactive material disintegration is independent of physical and chemical conditions. The number of atom that break up at any instant is proportional to the number of atoms present at that instant. Let…

E equal to mc squared derivation

Here is how we derive mass energy equivalence Force is defined as rate of change of momentum i.e., ….. (1) According to the theory of relativity, both mass and velocity are variable. Therefore ….. (2)…

The General Theory of Relativity

The special theory of relativity is valid only for inertial systems i.e.  Systems moving with constant relative velocity.  According to the first postulate of special relativity “the laws of physics may be expressed in equations…

Properties of Gamma rays

are electromagnetic waves of short wavelength and high frequency. The wavelength of range from 0.005 Angstrom to 0.5 Angstrom. They travel with velocity of light and are not charged particles like alpha or beta rays….

Properties of beta rays

has negative charge and its mass is equal to that of an electron. All emitted from a substance have big range of velocities anywhere from 0.3c to 0.9c where c is the speed of light….

Properties of Alpha particle

An alpha particle is nothing but a helium nucleus consisting of two protons and two neutrons with two unit of positive charge. particle coming out of a radioactive substances have very high velocity which might…

Natural radioactivity

In studying the florescence and phosphorescence of compounds irradiated with visible light, Bacquerel, in 1896, performed a crucial experiment which led to a deeper understanding of the properties of the nucleus of an atom. After…

Special Relativity

In 1905 Albert Einstein purposed how measurement of time and space are affected by motion between an observer and the object that is being observed. He called this theory the theory of Relativity and there…

Heisenberg’s uncertainty Principle

The statement of Heisenberg’s uncertainty Principle is something like this “it is impossible to determine precisely and simultaneously two complementary variables to arbitrary accuracy.” These pairs of variables are called canonical conjugate and example of…
