Minimum Size OF mirror required to see full image

Find the minimum size of mirror required to see the full image of a wall behind a man standing at the centre of room, where H is the height of wall.

Show that the minimum size of a plane mirror required to see the full image of an observer is half the size of that observer.

A student of height 1.9 m can see his full image in a plane mirror fixed on a wall. His eyes are 1.85 m from the floor level. What is the minimum length of the plane mirror required to get the full image of the student ?

Assertion : When the object moves with a velocity vec(v ) , its image in the plane mirror moves with a velocity of -5 vec( v ) . With respect to the object , Reason : the minimum height of the mirror to be required to see the full image of man of height h is (h)/(3)

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.

Find the minimum height of a mirror required to see the complete wall behind him.

The average size of an Indian face is 24xx16 cm^(2) . Find the minimum size of a plane mirror required to see the face completely by : (i) one eyed man (ii) tow eyed man. (Distance between eyes is =4 cm )

Figure shows an object AB and a plane mirror MN placed parallel to object. Indicate the mirror length required to see the image of object if observer's eye is at E .
