The US dropped 2 bombs on Japan on 6th august and 9th august.
Nuclear bombs were used for the first time in the war.
Actually, there are many ways of making a nuclear bomb.
First is the nuclear Fission reaction, Where one nucleus explodes and Splits into 2 small nuclei So much energy is released, and the reason for the splitting is that we throw a neutron on it. And it gives out neutron too. When a bomb is made this way, then it is called a normal nuclear bomb.
The second way is nuclear fusion, Where we create an environment of so much energy. And then 2 nuclei combine to make a nucleus, and it releases so much energy and neutrons. If all these reactions are not controlled then they become an Uncontrolled Chain Reaction. And so much energy is released due to its constant repetition. In fact, The energy from the sun comes to us due to nuclear Fusion only, and when a bomb is made this way, then it is called a thermonuclear bomb.
And sometimes, bombs are made through the combination of these 2 too.
