Answer 1

Answer:

$\huge\underline\mathfrak\red{❥Answer}$

Explanation:

Sharp shadows require a point source of light. Fluorescent lights usually are a tube, nowadays a curly tube, but a tube nevertheless.

Even the sun doesn’t produce a sharp shadow. If you look closely at a shadow produced by the sun you will see that it is fuzzy at the edges. This fuzzy area is the same width as the sun appears to be in the sky. NOTE: Don’t look at the sun, it could blind you, but the moon is approximately the same size, measure that instead.
