Q5 Despite having vision, dolphins use echolocation to identify and locate objects in the water in more detail. They emit ultrasonic pulses (very high frequency) whose rays obey the principle of rectilinear propagation. as do light rays. Glass has excellent reflective power for ultrasonic pulses. As the glass dome shown in the image is spherical and perfectly smooth, it behaves like a spherical mirror for the ultrasonic pulses emitted b the dolphin and reected irregularly in the sh. After undergoing regular reection in the dome, these pulses arrived at the dolphin as if they were emitte- by a sound image that was identied by the dolphin's ultra-hearing. As his brain couldn't differentiate 1 image of the sh from the real sh, he attacked the image as it was closer. Rd \\L Answer the questions a} Assemble a sketch that shows how the ultrasonic rays (which obey the same light propagation rule) ti came from the sh and reected off the dome formed the image. With this sketch, classify the image a: direct or inverted, real or virtual, and enlarged or reduced. b) if the situation obeys the Gaussian conditions, the sh is t] cm from the vertex and the radius of curvature of the dome is 31) cm, what is the value of the transverse linear magnication of the image
