- If we hold a transparent object in the Sun,can we see anything on the ground that gives us a hint that we are holding something in our hand?
- Changing the colour of the opaque objects does not change the colour of their shadows. What happens if we place an opaque object in the coloured light?
No we will not be able to see any image on holding a transparent object in the sun.
