Question

A full-length image of a distant tall building can definitely be seen by using?


Open in App
Solution

Convex mirror

  1. As we all know, a convex mirror's image is always smaller than the object's size, resulting in an erect and fictitious image of the thing.
  2. A diverging mirror is another name for it.
  3. It is also utilized as a rear view mirror in vehicles because it covers a large area behind the mirror.
  4. Demonstrating with the help of a diagram

A full-length image of a distant tall building using a convex mirror

  1. A ray of light AD running parallel to the major axis is reflected along with DX when a tall building AB is at a distance from the mirror. When DX is traced backwards, it appears to come from F.
  2. Another ray, AE, is reflected back along with EA as it travels towards the centre of curvature (C). When created backwards, these two diverging rays DX and EA appear to cross at A'.
  3. As a result, the image of the building generated is imaginary, upright, decreased and behind the mirror.
  4. Using a convex mirror, the full-length image of the distant tall building may be clearly viewed.

Hence, a full-length image of a distant tall building can definitely be seen by using a convex mirror.
