I was reading through a chapter named 'Solid state' in the NCERT Chemistry book.
I learnt about anisotropy of crystalline solids.
And what I understood was, you measure a certain property of that solid in one direction and it could be X while you measure it in the other direction it could be Y.
I then learnt about how a solid could show the property of birefringence.
My question : So does that mean, even electrical conductivity isn't the same in all directions? Does that mean a copper wire is going to conduct differently in different directions? How is that possible? It feels impossible? Does that mean different copper wires conduct differently?
I understand the last part is like a chunk of questions altogether and our community doesn't like that, but then it is basically having the same origin with just a little counter questions kinda? so I just let that be. I believe the contributors can understand what confusion I'm dealing with if I ask it like that.
