Where appropriate draw the proﬁle and ﬁnd the speed and direction of motion. 5. A small goldﬁsh is viewed through a spherical glass ﬁshbowl 30 cm in diameter. Deter-mine the apparent position and magniﬁcation of the ﬁsh’s eye when its actual position is (a) at the center of the bowl and (b) halfway between the center and the glass, along the line of sight, nearest to viewer. Assume that the glass is thin enough so that its eﬀect on the refraction may be neglected....
