A torch is placed at two different positions A and B, one by one, as shown in Fig. 11.9.
The shape of the shadow obtained in two positions is shown in Fig. 11.10.
Match the position of the torch and shape of the shadow of the ball.
A → a;
Position A will form the shadow ‘a’.
B → b
Position B will form the shadow ‘b’.
As the position of torch changes, change in the shape of the shadow will be observed.
