Right Answer is: B

SOLUTION

CONCEPT:

  • 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 2 is correct.

 

  • A concave mirror is used in the headlights of a vehicle and in the tourches.
  • A dentist also uses a concave mirror.
