Question

Dark patches formed behind an opaque object when light is obstructed by it are known as _______.

• A. dotted images
• B. shadows
• C. clear images
• D. images

Answer 1

The correct option is B shadows

When light falls on an opaque object, it does not allow it to pass through.

As a result, it obstructs the light from falling on the area behind it. Because of no light or less light, this area appears darker than its surroundings. This dark patch is known as the shadow.
