Question

From the following objects,which object gives dark shadow in front of torch?
1. glass jar
2. a wax paper
3.glass full of water
4. wooden duster

Answer 1

Every object can give out a shadow when it is in the dark and when a light source is directed towards it.

For this phenomenon to happen, we must be able to think of what the object is made up of, whether it has a mass, whether it is transparent and such factors.

So out of the answers given here the correct answer is the wooden duster which has a higher density with a higher mass.
