If the object is opaque to the frequency of light impinging on it, some of the light will be reflected and the rest will be converted to heat in the opaque object.
you need eyes a blocked path a light source. the light shines on the object blocking the path and reflects on the ground behind the objet and that is what you need to see a shadow
If the object is opaque to the frequency of light impinging on it, some of the light will be reflected and the rest will be converted to heat in the opaque object.
A Shadow is the absence of light next to an area of light. The absence of light is caused by an object that is in the direct path of light so that light cannot reach the area that the shadow is in. Light cannot go around an object and is therfore blocked by objects creating an absence of light that is proportional to the object that is blocking the light.
Depends on the surface of the object that the light is projected on. If the object has a polished surface like an inoxidable steel, or the object is a mirror, the light will produce a reflexion or the light comes back when it hits the mirror. Behind any object, is formed a shadow, since such object is not a glass.
well if the path of light is undisturbed by an object since the earth is spherical in shape, the light will go around the earth again and again untill the ray of the rectillinear propogation is disturbed.

shadow is a black areashadow is formed when a opaque object is come in the path of lightWhen light passes through opaque object, some of it would be blocked and form a shaedow.The shadow is formed according to the shape of the object as light moves in straight line.When light source is blocked by an opaque /translucent object a black spot is formed on the opposite side of the light source ...that black spot is called shadow.CHARACTERISTICS OF SHADOWS?black in colour .?outline of structure of the object.?size depends upon the light source and the object.?always forms on the opposite side of the light source .

Shadows appear because a light source is blocked by an object. For example, by standing outside on a sunny day, a person's body obstructs the sun's path of light and thus is unable to allow the light source to pass through, causing a 'dark spot' on the ground in the shape of their body.

We need an source of light, an opaque object blocking the path of light, a screen behind the opaque object.
A mirror
