Question100f10 _/1 E Current Attempt in Progress In the gure, a sh watcher at point P watches a sh through a glass wall of a sh tank The watcher is level with the sh; the index of refraction of the glass is 8/5, and that of the water is 4/3. The distances are d1 = 9.85 cm, d2 = 4.39 cm, and d3 = 7.11 cm. (a) To the sh, how far away does the watcher appear to be? (Hint: The watcher is the object, Light from that object passes through the wall's outside surface, which acts as a refracting surface. Find the image produced by that surfaceThen treat that image as an object whose light passes through the wall's inside surface, which acts as another refracting surface. Find the image produced by that surface, and there is the answert) (b) To the watcher, how far away does the sh appear to be? (a) Number n Units V (b) Number a Units v
