Boojho and Paheli were given one mirror each by their teacher. Boojho found his image to be erect and of the same size whereas Paheli found her image erect and smaller in size. This means that the mirrors of Boojho and Paheli are, respectively (a) plane mirror and concave mirror. (b) concave mirror and convex mirror. (c) plane mirror and convex mirror. (d) convex mirror and plane mirror.

Answer: (c) plane mirror and convex mirror.

The plane mirror always forms an image of the same size and erected image. Convex mirror forms erected and smaller images.

Plane mirror

The image formed by a plane mirror is always virtual and erect. The images formed from plane mirrors are the reflected images in their normal proportions but reversed from left to right. These are the most widely used mirrors.

The image formed by a plane mirror has certain characteristics.

The image formed in a plane mirror has the following features.

  • It is virtual
  • The image is laterally inverted.
  • It is erect and of the same size as the object
  • The size of the image is the same as the size of the object.
  • The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror.

Convex mirror

Convex means rounded or curved like the exterior of a circle or sphere. Also called a fisheye or diverging mirror.

  • The image formed by a convex mirror is virtual, erect and diminished.
  • Image cannot be projected on a screen as they are virtual.
  • Convex mirrors are used as side view or rearview mirrors in vehicles as they cover a wider area of view.
