Riya wants to install a mirror around the corner of her bungalow such that the vehicles coming from around the corner are properly visible. Which mirror should she use?

Riya should use a convex mirror. A convex mirror is a diverging mirror that is bulged outwards. It forms virtual and erect images of the objects irrespective of the distance of the objects from the mirror. Due to this small images can be seen in the mirror as a result of which many objects can be seen simultaneously. That means a convex mirror gives a wider view, therefore it is installed around the corners of societies and bungalows, in order to ensure that the road and the vehicles are properly visible to avoid accidents.
