A telescope has an objective of focal length 200 cm and eyepiece of focal length 5 cm. Calculate its magnifying power when the final image is formed (a) at infinity and (b) at distance of distinct vision.

A telescope has an objective of focal length 100 cm and an eyepiece of focal length 5 cm. What is the magnifying power of the telescope when the final image is formed at the least distance of distinct vision ?

A telescope has objective and eyepiece lenses of focal lengths 150 cm and 5 cm, respectively. Calculate the magnifying power of telescope when the final image is formed (a) at infinity and (b) at the least distance of clear vision.

A small telescope has an objective lens of focal length 140 cm and eyepiece of focal length 5.0 cm. What is the magnifying power of the telescope for viewing distant objects when (a) the telescope is in normal adjustment and (b) the final image is formed at least distance of distinct vision ?

A small telescope has an objective lens of focal length 140 cm and an eyepiece of focal length 5 cm. What is the magnifying power of the telescope for viewing distant objects when the final image is formed at the least distance of distinct vision(25cm).
