when is a shadow formed ?
A source of light, an opaque object and a screen are needed to form a shadow.
An opaque object blocks the light falling on it.
This creates an area of darkness on the side of the object away from the source of light.
A translucent object also creates a faint area of darkness.
An area of darkness formed by an opaque object obstructing light is called a shadow
Light can form the shadows of opaque objects because of its rectilinear propagation.
