A catfish is spotted at the bottom of a creek. The depth of the water is 2 m. A hunter (with no knowledge of optics) fires a rifle shot, directly aimed at the catfish. The bullet strikes the water at an angle of 40° to the water. Assume that the bullet is not deflected by the air/water interface, what is the distance from the bullet hole at the bottom of the creek to the catfish? A) 0.88 m B) 0.97 m C) 0.49 m D) 0.56 m E) 0.73 m
