Question

Convex Mirrors are used as rear-view mirrors in cars and motor-vehicles due to which of the following characteristic property?
1. It forms inverted image of the object
2. It forms real image of the object
3. It forms larger image of the object
4. It forms a smaller image as compared with the object

Answer 1

Correct Answer - Option 4 : It forms a smaller image as compared with the object

The correct answer is It forms a smaller image as compared with the object.

• A convex mirror, also known as a diverging mirror, is a mirror in which the reflective surface bulges toward the light source.

• A convex mirror reflects the light outwards and is therefore not used to focus light.
• Convex-mirrors are used as rear-view mirrors in cars and motor-vehicles.
• This is because the image formed by the convex mirror is always erect, virtual and smaller than the object which helps drivers to see other vehicles coming up behind them.
