Answer

Soln:

Two possible ways in which the real image of a distant tree can be obtained are given below :

  1. By using a concave mirror and a screen- By using a concave mirror, a real image is formed if the distance between the mirror and the object is beyond the focus.
  2. By using a convex lens and a screen- In a convex lens, when the object is far away from the lens, the image is very close to the lens forming a real and inverted image.
