What causes the λ (or lambda shape) in a shockwave? I heard it had something to do with the interaction between the shock and the boundary layer. If so, how do they interact and why does it make the signature λ symbol?

If someone could explain it in an easier way to understand, I’d appreciate it, thanks.

I will edit this question to add the link to where I saw that. Can’t seem to find it right now.
