Which mirror is preferred as a rear-view (wing) mirror in vehicles because of its wider field of view? Correct Answer Convex

Option 1 is the correct answer: Convex mirror is used as a rearview mirror in the vehicle.

CONCEPT:

  • Plane mirror: This mirror is straight without any inward or outward curve.
    • It forms a virtual image and upright image which is of size as same as the object.
    • The bathroom mirrors are an example.
  • Concave mirror: The mirrors curved inside on the reflecting side are called concave mirrors.
    • These mirrors produce a real, inverted, and magnified image of the object.
    • Thes are used in reflecting telescopes, shaving mirrors, and ophthalmoscope.
  • Convex mirror: It is an outward curved mirror that produces a diminished image.
    • Convex mirrors either diverge a parallel beam of light into all directions or gather light from all directions and produce a parallel beam out of it.

EXPLANATION:

  • Following are the reasons as to why a convex mirror is used as a rearview mirror in the vehicle

  • The image formed by the convex mirror is virtual and erect in contrast to that of the real but inverted image of the concave mirror.
  • It gathers light from all directions and aligns it as a parallel beam so that it provides a wider view to the viewer. That's why the convex mirror is used as a rear-view mirror in vehicles. So option 1 is correct.
