Laser is a potential energy source for inducing which type of reaction?
Correct answer: D. Fusion
- A. Radioactive
- B. Fission
- C. Ionization
- D. Fusion
Explanation
The correct answer is D) Fusion. Laser technology can be used in fusion reactions, such as in inertial confinement fusion, where lasers provide the energy needed to heat and compress the fuel to initiate fusion. Option A) Radioactive is incorrect because radioactivity is a spontaneous process that does not require external energy. Option B) Fission is incorrect because fission reactions are typically initiated by neutrons. Option C) Ionization is incorrect because, although lasers can ionize substances, they are not primarily used as a source of energy to initiate chemical reactions.

About Composition of Atomic Nuclei
Atomic nuclei contain positively charged protons and electrically neutral neutrons, collectively called nucleons. Questions use atomic number, mass number and nuclear notation to identify isotopes, isobars and isotones, and may connect nuclear composition with nuclear charge, mass defect, binding energy and the stability of the nucleus.
