Answer 2

Answer:

Explanation:

* A zero shadow day is a day on which the Sun does not cast a shadow of an object at noon, when the sun will be exactly at zenith. Zero shadow day happens twice in a year for the places between +23.5 and -23.5 degrees of latitude.

* We cannot see a shadow at night because there is no source of light. For a shadow to be formed we need a source of light, without it no shadow will appear. we cannot see the shadow properly because there is no light at all only when moon is there that time only some light comes but often we shadow.

* Simply speaking, a shadow is an absence of light. If light cannot get through an object, the surface on the other side of that object (for example, the ground or a wall) will have less light reaching it. A shadow is not a reflection, even though it is often the same shape as the object.
