Question

What can you say about the edges of the shadow?

• A. They are blurry but distinct
• B. None of these
• C. They are sharp and distinct
• D. They are different from the object

Answer 1

The correct option is C

They are sharp and distinct

A shadow is a region where light from a light source is obstructed by an opaque object. When a single source of light is present, the screen behind has a clear dark region due to obstruction of light forming a sharp shadow. But, when multiples sources are present, a part of the screen is partially dark, and a part of the screen is completely dark. This causes the formation of blurred shadow.
