Define magnifying power of a telescope. Write its expression.
A small telescope has an objective lens of focal length 150 cm and an eye piece of focal length 5 cm. If this telescope is used to view a 100 m high tower 3 cm away, find the height of the final image when it is formed 25 cm away from the eye piece.

A small telescope has an objective lens of focal length 150 cm and and eye piece of focal length 5 cm . If his telescope is used to view a 100 m high tower 3 km away, find the height of the final image when it is formed 25 cm away from the eye piece.

(a) Define magnifying power of a telescope. (b) Write its expression. A small telescope has an objective lens of focal length 150 cm and an eye piece of focal length 5 cm. If this telescope is used to view a 100m high tower 3 x 10^(5) cm away , find the height of the final image when it is formed 25 cam away from the eye piece.
