Question

The explosion of hydrogen bomb is based on the principle of:
A. Uncontrolled fission reaction
B. Nuclear fusion reaction
C. Controlled fission reaction
D. Photoelectric effect

Answer 1

Hint: In order to solve such problems one needs to know that explosion of hydrogen bombs happens because of the reaction which is uncontrolled. Knowing this will solve your problem and you will get the right answer.

Complete step-by-step answer:

If we look at the options provided we are very clear that photoelectric effect is not the answer to this problem of hydrogen explosion.

Explosion of a hydrogen bomb is carried out by an uncontrollable fusion reaction. Here uncontrollable fusion reaction means nuclear fusion reaction. Nuclear fusion is a process where nuclei of two atoms combine to form a heavier nucleus. This reaction is unstoppable and is very dangerous for life on earth. It doesn’t stop even if we bury the system of this reaction deep under the ground.

The correct answer to this problem is nuclear fusion reaction.

Hence, the correct option is B.

Note: This is a very vast concept since nuclear power carries the highest energy than anything in the world. Here generally at our level we study about two atoms Uranium and Thorium and their isotopes. Hydrogen explosion bombs are also referred to as thermonuclear weapons. They rely on fusion reactions between the two isotopes of hydrogen deuterium and tritium. These bombs are very powerful bombs. Hydrogen bombs are 3000 times the blast used in Hiroshima. The process involved in Hydrogen bombs is fusion which releases neutrons much faster than a fission reaction.
