Question

Which of the following are necessary for the formation of a shadow?

(More than one answer is correct)

• A. A source of light
• B. A transparent object
• C. A dark coloured object
• D. An opaque object

Answer 1

Answer: (A), (D)

The correct options are
A A source of light
D An opaque object

We just learnt that certain objects kill our light travellers. These objects form a shadow when placed in the path of light.

These objects are called opaque objects. Recall that these objects don't let light pass through. This is why they create a shadow.
