Question # 1

What information if revealed by the length and shape of track of an incident particle in Wilson Cloud Chamber?

Ans 1: In a wilson cloud chamber
1. Alpha particle have larger mass and greater ionizing power so its path is straight.
2. Beta particle have less mass and less ionizing power,so its path is thinner shorter and discontinuous.
3. Gamma particle have no mass and high penetrating power,so its leaves no definite track along its path,

Question # 1

Wh Geiger counter is not suitable for fast counting?

Ans 1: Geiger counter is not suitable for fast counting because of its longer dead time.The positive ions take several time as long to reach the outer cathode,because positive ions are very massive than the electrons.During this time further incoming particle can not be counted,This time is called as the dead time of counter which delays fast counting system.

Question # 1

What is the function of control rods in nuclear reactor?

Ans 1: Controls rods made of Cadmium or Boron are used for the control of number of neutrons,so that of all the neutrons produced in fission ,only one neutrons produces further fission reaction.
In case of emergency or for repair purpose control rods are used to stop the chain reaction and shut down the reactor.
