Correct Answer - Option 2 : Distance

The Correct Answer is Distance.

  • Distance is a numerical measurement of how far apart objects or points are. 
  • In physics or everyday usage, the distance may refer to a physical length or an estimation based on other criteria.
  • The distance from a point A to a point B is sometimes denoted as. 

  • Magnetic force, attraction, or repulsion arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
  • In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface.
  • The SI unit of magnetic flux is the weber and the CGS unit is the maxwell.
  • Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye.
  • Visible light is usually defined as having wavelengths in the range of 400–700 nm, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths).
