Once the light direction is known, what most strongly affects the length of a cast shadow?

Answer and explanation

Correct answer: Height of the light source

A cast shadow follows the direction opposite the light and changes length according to the light’s elevation. With the same general direction, a low light source produces a longer shadow, whereas a high source produces a shorter one. Therefore option A is correct. Pencil brand and paper colour affect appearance, not the geometric length; texture alone is insufficient.
