3. It is possible to cast multiple shadows of an object at the same time. Try to understand how this can be done and try to create this on your own. Observe the intensity of the shadow in this case. Observe the players in a day-night cricket match.
4. Observe and understand how and why the length of the shadow of a light pole changes during the day.
