5. A fish tank is filled with water of 1.5 m deep. A fish is swimming around at the bottom of the tank.

(a) If you are looking down into the tank from above, what is the apparent depth of the fish?

(b) Draw a diagram showing the real and apparent depth of the fish in water tank. (refer to Fig. 7).
