Overview         (For age - group : Below 16 )

How does our shadow vary as the sun rises and sets, this is same principle by which our ancestors used to tell time by using "sundial". This science animation (optics) software gives in-depth information about variation of shadows and is very useful for students and teachers.

Details of the animation/ movie /software

Shadows are formed when the sunrays are blocked by objects. Depending upon the relative positions of the light source and the object the length of the shadow keeps varying. In case of Sun, during the daytime the position of the sun in the sky keeps changing and hence the amount of sunlight getting blocked also varies. Consequently, the sunrays blocked by objects vary and hence the length of the shadow also varies. It is observed that the length of a shadow is maximum when the sun is at low altitude during mornings and evenings and is minimum during noon when the sun is overhead.

If you are still unclear about the concepts, please refer the animation.
