Answer:
m = 312.5
Explanation:
Given that,
The focal length of the objecive lens, [tex]f_o=1\ cm[/tex]
The focal length of eye piece, [tex]f_e=2\ cm[/tex]
length of the tube, L = 25 cm
We need to find the magnitude of the overall magnification of the microscope. It is given by the formula as follows :
[tex]m=\dfrac{L}{f_o}\times \dfrac{D}{f_e}[/tex]
D = 25 cm
So,
[tex]m=\dfrac{25}{1}\times \dfrac{25}{2}\\\\m=312.5[/tex]
So, the overall magnification of the microscope is 312.5.
