A small telescope has an objective lens of focal length `144 cm` and an eye-piece of focal length `6.0 cm`. What is the magnifying power of the telescope ? What is the separation between the objective and the eye-piece ?

Explanation

Here `f_(o) = 1.44 m = 144 cm, f_(e)= 6.0 cm, m = ?`
Magnifying power of the telescope,
`M=(f_(o))/(f_(e))=(144)/(6)=24`
