Answer:
1. Shadows are always formed on the opposite side. Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.
2. Shadows are formed because light travels in straight lines. ... Shadows are formed when an opaque object or material is placed in the path of rays of light. The opaque material does not let the light pass through it

a source of light.
an opaque object.
a screen or surface behind the object.
