Question

how does shadow form​

Answer 1

Answer:

When the rays reach Earth, they hit whatever is in their path. If the object they hit is opaque, the light cannot pass through, and a shadow forms. Simply speaking, a shadow is an absence of light..

Answer 2

Explanation:

Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. This results in an area of darkness appearing behind the object. The dark area is called a shadow.
