This ray exits from the bowl unchanged in direction. A ray from the top of the fish to V is refracted to bend away from the normal. Its extension back inside the fishbowl determines the location of the image and the characteristics of the image. The image is upright, virtual, and enlarged. C O I V FIG. Q36.15 Q36.16 Because when you look at the in your rear view mirror, the apparent left-right inversion clearly displays the name of the AMBULANCE behind you.
