Question

An object, pointing upwards, is placed outside the focal point F_2 of a thin diverging lens. A student is using the diagram shown above and the graphical method to predict the image of the arrow. To draw a principal ray. which direction should the student follow? Draw a ray from point Q through F_2 to the lens, then bend it so it is horizontal. Draw a ray from point P to any position on the lens, then bend it so it is horizontal. Draw a ray from point Q to the center of the lens, then bend it so it is horizontal. Draw a horizontal ray from point Q to the lens, then bend it so it appears to diverge from F_2.

Explanation / Answer

To draw principal ray, Draw a horizontal ray from point Q to the lens then bend it so it appears to diverge from F2
