Lines of Vigor, do they behave like light waves?
Brandon Sanderson
Yes.
KalynaAnne
So a higher frequency means it’s better at penetrating, lower frequency transfers energy and moves stuff?
Brandon Sanderson
Yes.
Ben McSweeney
Nice, I didn't know that one.
KalynaAnne
So, when they bounce off Lines of Forbiddance, do they follow laws of reflection?
Brandon Sanderson
Yes.
Ben McSweeney
They should always reflect at the same angle. Think of, like, a pool table.
KalynaAnne
If a Line of Vigor is moving from concrete onto asphalt, is it changing?
Brandon Sanderson
It's going to act like light transferring to a new medium.
KalynaAnne
So it refracts?
Brandon Sanderson
It's going to-- Yeah, it's going to refract.
KalynaAnne
So it changes speed as it moves?
Brandon Sanderson
Yep. So you get a different wavelength, or whatever, once transfers onto a new medium.
