Question 7 A dolphin was trying to eat a fish near a submarine. The dolphin gave up eating that fish and attacked the glass dome of the submarine. The submarine's crew did not understand what happened, because they've never seen dolphins do that. the biophysicist on board presented his hypothesis. Despite having vision, dolphins use echolocation to identify and locate objects in the water in greater detail. They emit ultrasonic pulses (very high frequency) whose rays obey to the principle of rectilinear propagation, as well as light rays. The glass It has excellent reflective power for ultrasonic pulses. Like this glass dome is spherical and perfectly smooth, it behaves like a spherical mirror for the ultrasonic pulses produced by the dolphin and irregularly reflected in the fish. After undergoing regular reflection in the dome, such pulses arrived at the dolphin as if they were emitted by a sound image that was identified by the dolphin's ultra-hearing. As his brain did not differentiate between the image of the fish and the real fish, he attacked what was closest: the image. (Just a context history) Assuming that the marine biophysicist hypothesis is correct, apply your knowledge of geometric optics to the situation and get the which is requested in the items below, presenting all the calculations. a) Assemble a sketch that shows how the ultrasonic rays that came of the fish and reflected in the dome form the image. Use this sketch to classify the image as straight or inverted, real or virtual and enlarged or reduced. b) If the situation meets the Gaussian conditions, the fish is 60 cm of the vertex and the radius of curvature of the dome is 30 cm, what is the value of the transverse linear magnification of the image
