The image formed by a plane mirror is always virtual, erect, and of same size as the object. Image formed by a plane mirror is virtual, i.e., it is formed behind the mirror without the actual intersection of light rays. It is erect, which means up straight. The image is laterally inverted, i.e., it is reversed from left to right.

Characteristics of image formed by a plane mirror:

  1. The image formed is virtual.
  2. It is of the same size as the object.
  3. The image is laterally inverted.
  4. The image is erect.
  5. Distance of image from mirror will be the same as distance of the object from the mirror.

    A wire of length \(L\) is bent round into (i) a square coil having \(N\) turns and (ii) a circular coil having \(N\) turns. The coil in both cases is free to turn about a vertical axis coinciding with the plane of the coil, in a uniform, horizontal magnetic field and carry the same currents. Find the ratio of the maximum value of the torque acting on the square coil to that on the circular coil.
