Characteristics of the image formed by a plane mirror

(i) Image formed by a plane mirror is as far behind the mirror as the object is in front of it and it is always virtual.

(ii) The image produced is laterally inverted.

(iii) The minimum size of the mirror required to see the complete image of the object is half the size of the object.

(iv) If the mirror turns by an angle θ, the reflected ray turns through an angle 2θ.

(v) If an object is placed between two plane mirrors inclined at an angle θ, then the number of images formed is: n = 3600/θ – 1
