Question

Where does fusion occur naturally?$(5.6)$

Short answer

There are several political, social, environmental, and ethical concerns in using the energy released by nuclear fusion to generate power, just as there are with nuclear fission.

Step-by-step solution

Step 1:     Introduction

In stars like our sun, fusion events occur spontaneously when two hydrogen nuclei fuse together at high temperatures and pressure to generate a helium nucleus.

Light, infrared radiation, and ultra violet radiation are examples of electromagnetic radiation that is released and subsequently travels through space.

    Explanation 

Nuclear fusion reactions take place in stars like our Sun in a variety of ways.

When the nucleus of a hydrogen-$2$atom (or deuterium) collides with the nucleus of a hydrogen-$3$atom (or tritium), a helium-$4$nucleus is formed, and a neutron is produced.

    Conclusion

Electromagnetic radiation is used to liberate energy.
