R = 0.4 m
f = - 0.2 m
v = ?
hi = ?
ho = 0.2 m
u = - 0.8 m
![1 over f equals 1 over v plus 1 over u
fraction numerator 1 over denominator negative 0.2 end fraction equals space 1 over v plus fraction numerator 1 over denominator negative 0.8 end fraction
fraction numerator 1 over denominator negative 0.2 end fraction equals 1 over v minus fraction numerator 1 over denominator 0.8 end fraction
1 over v space equals space fraction numerator 1 over denominator negative 0.2 end fraction plus fraction numerator 1 over denominator 0.8 end fraction
v space equals space fraction numerator negative 0.8 over denominator 3 end fraction space... left parenthesis I m a g e space d i s tan c e right parenthesis space
m space equals space fraction numerator negative v over denominator u end fraction space equals space h subscript i over h subscript o
bevelled fraction numerator negative begin display style fraction numerator left parenthesis negative 0.8 right parenthesis over denominator 3 end fraction end style over denominator negative 0.8 end fraction space equals space fraction numerator h subscript i over denominator 0.2 end fraction
h subscript i equals fraction numerator 0.4 over denominator 3 end fraction](https://images.topperlearning.com/topper/tinymce/cache/fbbba3163d9f2aad8103e97afe9cb7b3.png)
