Refractive~ index~ (\mu)   =  \dfrac{4}{3}

Let the coin be placed at point O

Let the height of beaker be AO = 16 cm

Let the apparent depth be AI

 \mu \:  =  \dfrac{Real \: depth}{Apparent \: depth}

 \dfrac{4}{3}  =  \dfrac{AO}{AI}

 \dfrac{4}{3}  =  \dfrac{16}{AI}

AI =  \dfrac{3}{4}  \times 16

\red{AI = 12~cm}
