Question

since human body is an opaque ,why it allows partial light to pass through when your finger is placed near a source of light​

Answer 1

Explanation:

• When an opaque object is placed in the path of light then light does not pass through the object. Light continue travels in a straight path until it bounces off the ground. Then, it will form a shadow.

• What happens when an object is placed in the path of light? Light travels in straight lines. It cannot bend to travel around objects; if it did we could see around corners! When light is blocked by an object a dark area or shadow is formed.
