The focal length of the objectives and the eyepiece of an astronomical telescope are `16cm`and`2cm` respectively .A planet is viewed with its help ,then

A

The angular magnification of the planet is`-800`

B

The image of the planet is inverted

C

the distance between the objectives and the eye piece of`16.02`

D

All the above

Text Solution

Verified by Experts

The correct Answer is:
4
`therefore` Distance between objectives and eyepiece
`=f_(0)+f_(e)=16.02m`
Angular magnification`M=-(f_(0))/(f_(e))`
or`M=(-16)/(0.02)=-800`
The image formed by a telescope is always inverted.
