Question

Suppose we wish to obtain the real image of a distant tree. Explain two possible ways in which we can do it.

Answer 1

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. In 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, real and inverted.
