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

Text Solution

Verified by Experts

`f_(0) = 144 cm, f_(e) = 6 cm " " therefore m = (f_(0))/(f_(e)) = (144)/(6) = 24 `
`L = f_(0) + f_(e) = 144 + 6 = 150 cm `
