Light Travels in Straight Lines, Right?

The fiber has two pieces to it. It has the cladding and it has the core. The core is that, that ultra fine piece of glass that we're actually using to send it in. Cladding is kind of a plastic wrapping for it if you like. And its purpose in life is, is again, it's a physics thing. But fair enough. We say more. No, I think about it. I'm good. Yeah. So yeah, when we're talking about how light goes along a fiber, we said light travels in straight lines, right? so literally any light that was coming in perfectly straight will kind of travel perfectly straight in a perfectly straight fiber.
