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

Question

Philoid · Accepted Answer

A real image is formed by concave mirror or convex lens.

in first possible way we can use a concave mirror and a screen , as concave mirror forms a real image only when object is at a distance to it, so concave mirror will produce real image of distant tree on the screen.

In second possible way we can use a convex lens and a screen. as convex lens forms a real image only when object is at a distance to it, so convex lens will produce real image of distant tree on the screen.
