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.
