A telescope has an objective of focal length 30 cm and an eyepiece of focal length 3.0 cm. It is focussed on a scale present at a distance of 2.0 m. For seeing with relaxed eye, calculate the separation between the objective and the eyepiece.
|Why this question?
Key Note:For seeing with relaxed eye, the final image should be formed at infinity. For this, the image formed by the objective should fall at the focus of the eyepiece.
