Collect pictures and write a short summary on the two different types of nuclear bombs mentioned above.

Answer:

Atomic Bomb (Fission Type) A nuclear weapon is an explosive device   that   derives   its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. Weapons whose explosive output is exclusively from fission reactions are commonly referred to as atomic bombs or atom bombs. In fission bombs, a mass of fissile material (enriched uranium or Plutonium) is assembled into a supercritical mass either by shooting one piece of sub-critical material into another or by compressing a sub-critical sphere of material using chemical explosives to many times its original density. The amount of energy released by fission bombs can range from the equivalent of less than a ton of TNT upwards of 500,000 tons (500 kilotons) of TNT.   (ii) Hydrogen Bomb (Fusion Type) The basic principle of this bomb is the idea that different parts of a thermonuclear weapon can be chained together in "stages", with the detonation of each stage providing the energy to ignite the next stage. This implies a primary section which consists of a fission bomb (a 'trigger'), and a secondary section which consists of fusion fuel. The energy released by the primary compresses the secondary through a process called "radiation implosion" at which point it is heated and undergoes nuclear fusion.
