A dolphin was trying to eat a sh near a submarine. The dolphin gave up eating that sh and attacked the submarine's glass dome. The crew of the submarine were left with no understanding of what happened, as they had never seen dolphins do this. The marine biophysicist on board presented his hypothesis. .1; if i W \\i. c) The dolphin's ultra-hearing interpreted that the size The apparent image of the sh was one-third the size appearance of the real sh, obeying the same proportion between the corresponding "viewing angles", adapted for ultrasonic rays. whereas the angles between the ultrasonic rays that reach the dolphin are very small, how far was the dolphin from the dome when did the dolphin's ultra- hearing make this interpretation? Tip: as the "viewing angles'I are very small, assume that the ratio between the actual sizes of objects and their distance from the observer is approx. equal to the angles in radians
