Q1: How do shadows change size as you move an object closer to the light?

[Answer]

A shadow is the dark region behind an object where the light cannot reach directly.

Shadows change size depending on the position of the object between the light and the place where the shadow falls.

A shadow gets bigger if you bring the object nearer to the light.

A shadow gets smaller if you take the object farther from the light.
