Parallax. Two people are sitting in a car driving along a road towards the
sun at sunset so that the sun is level with the car in the vertical
direction. Each person sitting in his or her seat is 1 metre to
either side of the centre of the car and there is a traffic light 100
metres directly ahead of the centre of the car.
a. What is the angle between the traffic light and the sun for the driver?
You may wish to draw a diagram to help you visualize this. I will
also describe the situation if asked.
b. Will the angle between the traffic light and the sun increase or
decrease as the car moves closer to the light?
