Does a ray always, sometimes, or never have a finite length?

a ray has one side ended while the other side runs forever
so it's never

Never. A ray extends forever from a given point.
A vector can have a finite length because the length is the finite magnitude of the vector. Though a vector looks like a ray, they are not the same.

Nope. A ray's got a infinite length that begins from it's endpoint.

Never. It goes on forever.
