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….

History of atomic theory

Somewhere around 440 BCE Democritus proposed that everything in the world was made up of tiny particles surrounded by empty space. And he even speculated that they vary in size and shape depending on the…
