Q1: Which way do the shadows point?

[Answer]

If there is a single source of light in a room, it will give you a single shadow.

The shadow will be small when you are almost underneath it, and it will get longer, the farther you are from it.

Your shadow may shrink and grow, but it always points towards the source of the light.
