Optical Instruments & the Eye

An observer looks at a distant tree of height $10$ m with a telescope of magnifying power of $20$ . To the observer, the tree appears

Show answer and solution

Answer: (c)

A telescope increases the angle subtended by the object at the eye: $\beta = M\alpha = 20\alpha$ .
The same angle would be produced if the tree were at $\dfrac{1}{20}$ of its distance; its size is unchanged.
So the answer is (c) 20 times nearer.
