Question
Chapter 8, Problem 12E
Interpretation Introduction
Interpretation:
The two designs, Fat Man and Little Boy, which were used to make a bomb are to be explained.
Concept Introduction:
The amount of substance needed for a self-sustaining fission reaction is called critical mass.
In fission reaction, there is release of neutrons and energy.
In an atomic bomb, the fission reaction is carried out in uncontrolled manner which leads to explosion.
