Light travels through fiber optics the same way it travels everywhere else, except when it scrapes against the inside of the cable it bounces off. Sort of like how a matchbox car goes down a plastic track. In fact, just like the toy car, the light will escape from the cable if it has to turn too quickly. The name for this maximum turn angle is called the "critical angle".
This "critical angle" is different depending on what kind of material is in your cable (glass, plastic, metal, etc) as well as what the cable is sitting in (Air, water, space, etc).

∙ 8y agoInterestingly enough light doesn't "bend" in an optic fibre. It reflects from the inner surface of the fibre back into the fibre material and skips along like that. Imagine a pebble tossed into a long bent and curved pipe down into a mine , it gets to the other end but by ricochetting off the sides, not but following a curved arc down the middle of the pipe

Are fiber optics a type of internet connection?
No, fiber optics are a transmission medium.
Why are infrared waves used in fiber optics?
This is because infrared can travel farther with less distortion, i.e., it has less attenuation.
Why should the light ray be reflected rather than refractive in fiber optics?
Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection. Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics. In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.
Does weather interfere with the transmission of a signal with fiber optics?
No, fiber optics are cables ran from underneath the ground. The weather will not affect it.
How is light used in fiber optics?
Light enter the optical fibre, and is totally internally reflected all the way along.
Why do signals in the fiber optics cables travel at the speed of light?
fiber optics transfer data at the speed of light because that's exactly what is transmitted through them... light. fiber optic cables are thin pieces of glass that transmit light pulses
What is the speed of light travel through fiber optics?
200,000,000 metres per second
Light travels through a thin glass fiber?
fiber optics
Are fiber optics a light source?
yes they r.
How fiber optics systems transmit light?
bc it does
What is an example of optics?
Some examples are Light bulb, fiber optics, laser surgury intruments.
What type of waves in fiber optics?
Light, typically IR.
What are fiber-optics?
Fiber optics are cables that are used to transmit data at the speed of light. This uis especially popular with Verizon FiOS services. for details on fios go to www.whyisfiosbetter.viviti.com
How do fiber optics work?
basically, the cable uses something called the critical angle, to keep light inside it. This means the cable can be bent while still allowing light to travel through it.
