Question

2. We saw that changing colour of opaque objects does not change the colour of
their shadows. What happens if we place an opaque object in coloured light?
You can cover the face of a torch with a coloured transparent paper to do this.
(Did you ever notice the colours of evening shadows just as the Sun is setting?)​

Answer 1

Answer:
