Question

A tank contains two different liquids which do not mix with each other as shown in figure. The lower and upper liquids are at depths $h subscript 1$ and $h subscript 2$ respectively. An object o is located at the bottom. When seen vertically from above, locate the position of image of o.

$\frac{h_{1}}{n_{2}} - \frac{h_{2}}{n_{1}}$
$\frac{h_{1}}{n_{2}} + \frac{h_{2}}{n_{1}}$
$\frac{h_{1}}{n_{1}} + \frac{h_{2}}{n_{2}}$
$\frac{h_{1}}{n_{1}} - \frac{h_{2}}{n_{2}}$

The correct answer is: $straight h subscript 1 over straight n subscript 1 plus straight h subscript 2 over straight n subscript 2$
