A fish is 6.0 cm from the front surface of a fish bowl of radius 27 cm. Where does the fish appear to be to someone in air viewing it from in front of the bowl? (Give your answer in cm.)

Where does the fish appear to be when it is 45.0 cm from the front surface of the bowl? (Give your answer in cm.)

（1）6*1.33=8cm

（2）45-27=18cm

18/1.33=14.5cm

（14.5+27）*1.33=52cm

就是个折射率的问题。。。
