Question

A person working on the transmission of a car accidentally drops a bolt into a tray of oil. The oil is $5.00$ cm deep. The bolt appears to be $3.40$ cm beneath the surface of the oil when viewed from directly above. What is the index of refraction of the oil?

Solution

The correct option is B $1.47$
We know
$ADRD=μBμ0μ0=( Observer refractive index )$
$\begin{matrix} \frac{3 \cdot 4}{5} = \frac{1}{μ} μ = \frac{5}{34} = 1.47 μ = 1.47 \end{matrix}$
so option $B$ is correct
