Answers
Answer:
yes
Explanation:
because the position of torch , screen, ball the shadow will appear
Three mistakes Ravi is doing which is becoming an obstacle in the path of the shadow formation are:
1. Placing the screen away very far away from the object - This will not a cast a shadow because the screen won't be able to catch the shadow or light.
2. Placing the source of light, the torch, away from the object, the ball - This way the torch will not be able to disperse the light and create it's shadow.
3. The beam of light from the torch is falling parallel to the screen on the ball - The ball in this case does not obstruct the whole light from the torch and the shadow is not formed.
If Ravi wishes to get a perfect shadow, he should keep all the screen, torch and ball in a straight line at equal intervals.
