Answer:
No shadow will be formed in either of the cases, except for the muslin cloth and plywood.i. Lighter image will be formed of a muslin cloth, as it is translucent, so the light will pass partially through it.ii. For the formation of the shadow, an object should be opaque, since the glass is transparent, shadow formation will not take place.iii. The sheet of plywood is an opaque object, thus, the perfect dark shadow will be obtained.
Hope it helps uh....
