Question

Give the reasons for the following : In front of an ambulance the word ‘AMBULANCE’ is written as

Answer 1

The word ambulance is written on the ambulance so that when the driver in front sees the word he should get to know that there is an ambulance behind him and give a way for the ambulance.

Complete step-by-step answer:
A vehicle contains a rear view mirror, which helps the driver to see the vehicles behind it, when travelling on a road.
The rear view mirror attached to a vehicle is a convex mirror. It is a convex mirror because it always forms a virtual image of an object in front of it. When a virtual image is formed by a mirror, the image can be in the mirror.
A convex mirror always forms an erect image. In addition, a convex mirror always forms a diminished image of the object. Since the objects in the mirror are small, the driver can see a view of a larger area behind him.
Therefore, when an ambulance is behind the vehicle, the driver can see the ambulance in the mirror. However, the image will be inverted horizontally. Therefore, to read the image of alphabets properly, the words must be written in such a way that are inverted horizontally.
Hence, the word ‘AMBULANCE’ is written as the way shown in the question.

Note: The distance of the image of the image formed by a convex mirror is more than the distance of the object from the mirror. Therefore, it is written on the mirror that the objects are nearer than they appear to be.
