Question

Which of the following is not used in the field of physics?

• A. Stock value
• B. Latent heat
• C. Nuclear fusion
• D. Refractive index

Hint:

Three of the four terms come from physics chapters on heat, nuclear physics and optics, one belongs to finance.

Answer 1

The Correct Option is A

We are looking for the one term among four that does not belong to physics.

1. Latent heat is used in the study of heat and thermodynamics, describing energy changes during melting, boiling and similar phase changes, a real physics term.
2. Nuclear fusion is the joining of small nuclei to release energy, the process that powers the Sun, part of nuclear physics.
3. Refractive index measures how much a transparent medium bends light, a standard optics quantity in physics.
4. Stock value describes the market price of a company's shares, a concept from finance and economics with no place among physics quantities.

So option A, stock value, is the term not used in physics.
