In a compound microscope, the image formed by the objective lens is at a distance of 3.0cm from the eye lens. Calculate the focal length of the eye lens
- 0.3cm
- 2.7cm
-
3.4cm
- 8.3cm
The correct answer is: C
Explanation
\(\frac{1}{f} = \frac{1}{u} + \frac{1}{v} = \frac{1}{3} - \frac{1}{25} = \frac{22}{75}\)f = 3.4cm
