To determine the minimum size of the plane mirror required to view a full image of an object, you need to consider the size and position of the object in relation to the mirror.
In this case, you have an object that is 160 cm high. To view the full image of this object in a mirror, the mirror needs to be tall enough so that the entire object can be reflected.
The height of the mirror will be the same as the height of the object. Therefore, the minimum size of the plane mirror required would also be 160 cm in height.
Keep in mind that the width of the mirror does not need to be the same as the height of the object. As long as the object can be fully reflected in the mirror without any parts being cut off, the width of the mirror can be smaller than the object itself.
