A thin convex lens made from crown glass $$\left( {\mu = {3 \over 2}} \right)$$ has focal length $$f$$. When it is measured in two different liquids having refractive indices $${4 \over 3}$$ and $${5 \over 3},$$ it has the focal lengths $${f_1}$$ and $${f_2}$$ respectively. The correct relation between the focal lengths is :
A
$${f_1} = {f_2} < f$$
B
$${f_1} > f$$ and $${f_2}$$ becomes negative
C
$${f_2} > f$$ and $${f_1}$$ becomes negative
D
$${f_1}\,$$ and$${f_2}\,$$ both become negative
