Question

Transparent objects do not cast shadows if we hold a transparent object in a sunlight do we see anything on ground which gives an idea something that we are holding something

Answer 1

Answer: no, In a simpler way, the object must be opaque or translucent to make a shadow. A transparent object will not create any shadow, as light will pass straight through the object, but such transparent objects do not allow all the light to pass through them, they still interact with light through refraction.
