A new theatre is being built, it will screen multiple short films on digital screens embedded in the walls around the foyer. One screen is 2 meters high and is positioned so that the bottom of the screen is 1 metre above your eye level.
a) Create a model that will allow you to find the horizontal distance from the wall on which the screen is positioned for various angles of vision (i.e the angle formed by your eye with the top and bottom of your screen)
(i) How far from the wall should you stand so that this angle of vision is maximum?
(ii) What is this maximum angtle?
(iii) Include a generalised form of your model using S(screen height), D(distance above eye level), what is the maximized angle of the general form?
b) On the wall opposite there is another screen which is only 1 metre high and also positioned with its base 1 metre above your eye level, directly opposite the first screen.
Develop a second model to represent this new situation
(i) Where should you stand to maximise your angle of vision?
(ii) What is this angle?
