A person wants to see AB part of his image. His eye level is at 1.8m above the ground. If he uses minimum size of mirror required for this, find the height of the lowest point of mirror above the ground.

A boy of height 1.5m with his eye level at 1.4m stands before a plane mirror of length 0.75 m fixed on the wall. The height of the lower edge of the mirror above the floor is 0.8 m. Then ,

Ramesh places a mirror on level ground to determine the height of a pole (with traffic light fired on it) (see the figure). He stands at a certain distance so that he can see the top of the pole reflected from the mirror. Ramesh's eye level is 1.8 m above the ground. The distance of Ramesh and the pole from the mirror are 1.5 m and 2.5 m respectively. If Ramesh's eye level is 1.2 m above the ground, then the height of the pole is:
