Given:
The focal length of the lens, f=3.12 m
The height of the film, h=0.30 m
The height of the image, h_i=0.83 m
To find:
The magnification of the lens.
Explanation:
The magnification of a lens is given by,
[tex]m=\frac{h_i}{h}[/tex]On substituting the known values,
[tex]\begin{gathered} m=\frac{0.83}{0.30} \\ =2.77\text{ } \end{gathered}[/tex]Final answer:
The magnification of the lens is 2.77
