What is the index of refraction of the tanks walls

Reference no: EM13282373

A particular fish tank filled with fresh water (n=1.33) has a coral reef sticker stuck to an exterior wall(outside of the tank). The tank's walls are 1.5 cm thick, but a goldfish inside the tank sees the sticker 0.7cm away from the water wall interface. What is the index of refraction of the tank's walls?
