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…

de Broglie’s Hypothesis

nuclear physics

De Broglie in 1923 suggested that wave particle duality must be universal, that is all material particles should also display a dual wave particle behavior. To put it in other words all material particles, just…

Bohr theory of atom

Bohr theory of atom is one of the initial achievement and application of quantum mechanics or old quantum mechanics as most would call it. It was able to explain the spectrum of hydrogen atom. Basic…

Photoelectric effect

Photoelectric effect

Photoelectric effect is one of the initial phenomena which proved the quantization of light. It was discovered by Hertz in 1887 and Thomson in 1899 confirmed that it was electron that was responsible for photoelectric…
