Answer:
The correct answer is option D
Explanation:
The odd one among the given four options:
- fermi
- angstrom
- nanometre
- light year
Is Light year.
All the given options are units to measure length.
While fermi, angstrom and nanometer are smaller units to measure length, a light-year is a comparatively much larger unit.
- A light-year is used to measure astronomical distances. When light travels some distance in one year at its characteristic speed that distance is said to be one light year.
- One light-year is approximately equal to 9.5 trillion kilometres.
- Fermi is the SI unit of length used to measure distances in sub-atomic particles.
- One fermi is equal to the quadrillionth of metres.
- Similarly, angstrom and nanometer are also smaller units of distance and are used to measure very minute substances.
- 1 fermi = 10⁻¹⁵ m
- 1 angstrom = 10⁻¹⁰m
- 1 nanometer= 10⁻⁹m
