Detailed explanation-1: -Hydrogen bombs cause a bigger explosion, which means the shock waves, blast, heat and radiation all have larger reach than an atomic bomb, according to Page 3 Edward Morse, a professor of nuclear engineering at University of California, Berkeley.
Detailed explanation-2: -A hydrogen bomb and an atomic bomb are both types of nuclear weapons, but the two devices are very different from each other. In a nutshell, an atomic bomb is a fission device, while a hydrogen bomb uses fission to power a fusion reaction. In other words, an atomic bomb can be used as a trigger for a hydrogen bomb.
Detailed explanation-3: -It uses the energy from a primary nuclear fission to set off a subsequent fusion reaction. The energy released by fusion is three to four times greater than the energy released by fission, giving the “hydrogen” bomb, or H-bomb, more power.
