Do vampires cast a shadow? Because if they cast a shadow, would they actually be able to see through themselves in a mirror, or would they just see a big void in the shape of their body as the light from behind them hits their body but not the mirror? π€
Ummm... Because shadows aren't a solid mass. They're just where light isn't. So even in a case where a vampire casts a shadow, it wouldn't matter, mirrors still work in the dark.
Mirrors work by reflecting light. If the light isn't passing through the vampire from behind to hit the mirror, it cannot reflect it. If a vampire casts a shadow, this implies that light does not pass through them. For them to not reflect in a mirror, but still be able to see what is behind them, light would need to pass through their body, which would mean they also would not cast a shadow.
We could say that vampires donβt have a material body and they just alter the wavelength of light that passes through them to project a living form towards the eyes of living observers. That way they could be visible without having a reflection.
Then they could give themselves a shadow by shifting the visible light from bright light sources into infrared or ultraviolet instead of blocking it as material objects do.
