A) \[5:3~\]
B) \[3:5\]
C) \[\text{2}:5\]
D) \[5:2\]
Correct Answer: B
Solution :
\[{{P}_{1}}+{{P}_{2}}=2D\] and \[{{P}_{1}}=5D\], so \[{{P}_{2}}=-3D\] For achromatic combination \[\frac{{{\omega }_{1}}}{{{\omega }_{2}}}=\left( -\frac{{{P}_{2}}}{{{P}_{1}}} \right)=\left( \frac{-3}{5} \right)=\frac{3}{5}\]You need to login to perform this action.
