Hydrogen bomb is based on the principle of (a) controlled fusion reaction (b) uncontrolled fusion reaction (c) controlled fission reaction (d) uncontrolled fission reaction

Answer»

(b) uncontrolled fusion reaction.

Explanation:

Thermonuclear fusion or hydrogen bombs explode with enormous power using uncontrolled self-sustaining chain fusion reactions. Deuterium and tritium, under extremely high temperatures, form helium providing the energy.

D + T → 4He + n

In principle, a mixture of D, T and 6Li heated to very high temperature and confined to a high density will start a chain fusion reaction, liberating an enormous amount of energy
