Answer 1

Answer:

your answer is c..........

Answer 2

The shadow of the boy is formed on the screen which reveals the following observation -

the opaque object must be placed between the source of light and the screen (Option c)

• There are broadly two essential conditions required for the formation of a shadow.
• First, the object must be opaque, that is, light should not be able to cross through it.
• Second, the path of light must be obstructed by the object. This implies that the object must be placed in between the source of light and the screen
• Hence, option c satisfies the required condition and is the right choice.
