What is meant by lateral inversion? Give an example to illustrateb its use in practice.
The phenomenon due to which left-hand side of an object appears as right-hand side of the object and vice versa is called lateral inversion.
For example, the word AMBULANCE is painted left-right inverted on the ambulance so that when the driver of a vehicle in front looks into his rear-view mirror, he can make out the word AMBULANCE quickly and give way.
