Find the index of refraction of the tanks walls

Reference no: EM13239064

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 2.0 cm thick, but a goldfish inside the tank sees the sticker 0.9 cm away from the water-wall interface. What is the index of refraction of the tank's walls?
