A cloud chamber is a simple device used to visualize radioactive particles. It was invented by a physicist named Charles Thomson Wilson, almost a 100 years before and for this amazing invention he was awarded noble prize in the year 1927. Now when charged particles, such as alpha particles or beta particles, pass through the chamber, They will form white cloudy streaks. These streaks are formed because of ionization. The alpha particles will form a dense streak which goes in straight line, While the beta particle will form thin streak which goes in zig zag pattern.
