You see a person in the distance. From Figure 1 assume the person of height 'AB' is reflected onto the retina through the nodal point 'n' as 'ab’. If AB is 2 m in height and 10 m from the nodal point n, what will be the size of the person ('ab’) on the retina in mm? Show your calculations. (Hint use basic trigonometry).
