- $ m = \frac{h'}{h} = \frac {f_2 B'}{f_e}$

- $ f_2 B = L $

- $\therefore . m = \frac {L}{f_e}$

- Angular magnification $m_o = \frac {D}{f_e} $ (already discuss)

- Compound Microscope (layout and ray diagram)

- L = Tube length

- $F_0$ = Focal length of objective

- $F_e$ = Focal length of eye piece
