A light ray propagates through an optical fiber by undergoing total internal reflection at the boundary between the core and cladding of the fiber. This allows the light to travel down the length of the fiber without significant loss in intensity. The core of the fiber has a higher refractive index than the cladding, which is what enables this total internal reflection to occur.

Explain the propagation of light through optical fiber and appilication of optical fiber as wave guide and sensor?
The concept of light propagation, the transmission of light along an optical fiber, can be described by two theories. According to the first theory, light is described as a simple ray. This theory is the ray theory, or geometrical optics, approach. The advantage of the ray approach is that you get a clearer picture of the propagation of light along a fiber. The ray theory is used to approximate the light acceptance and guiding properties of optical fibers. According to the second theory, light is described as an electromagnetic wave. This theory is the mode theory, or wave representation, approach. The mode theory describes the behavior of light within an optical fiber. The mode theory is useful in describing the optical fiber properties of absorption, attenuation, and dispersion
What is the difference between ray theory and mode theory of light?
mode theory assumes light to be a wave, but ray theory does not assume light to be either a wave or particle. ray theory is used to calculate properties like magnification or distance to the object or image in an optical system, where as mode theory is used find bandwidth, reflection coefficients and parallel polarization.
What are the terms and its meanings of light ray?
A light ray is a straight line used to represent the path along which light travels. It is an abstraction used to analyze the behavior of light in various optical systems. In optical terminology, light rays are used to trace the path of light and determine how it interacts with surfaces and lenses.
What can a ray be used to represent light in a ray diagram?
A ray can be used to represent the path that light travels in a ray diagram. It helps to illustrate how light reflects, refracts, or interacts with different optical elements such as mirrors or lenses. Rays are drawn as straight lines with arrows indicating the direction of light travel.
What is the name given to a change of direction of a ray of light?
The name given to a change of direction of a ray of light is called refraction. Refraction occurs when light passes from one medium to another with a different optical density, causing the light ray to bend.

What can you ay about the angle of incidence when a ray of light travels along and optical fiber?
1. The Angle of Incidence equals the Angle of Reflection. 2. The Angle of Incidence is very SHALLOW. The light travels almost parallel to the sides of the Fiber.
Differentiate between meridional rays and skew rays?
A meridional ray is a ray that passes through the axis of an optical fiber.A skew ray is a ray that travels in a non-planar zig-zag path and never crosses the axis of an optical fiber.
When is light a ray and when is it not?
Rays are used to model the propagation of light through an optical system
Tell you the definition of mode in optical fibre communication?
Modes are different energy components(or rays) of light traveling down an optical fiber waveguide. (Instead of just single energy rays) Since it is practically impossible to separate a monochromatic light(ray) we have different wavelengths and hence different energy light waves(or rays).
In the real world in what are lasers used?
DVDs and Blu-Ray, optical devices, fiber optics, laser cutting

What are the Elements of optical fiber communication link?
If light meets the inner surface of the cladding (the core - cladding interface) at greater than or equal to Qc then TIR occurs. So all the energy in the ray of light is reflected back into the core and none escapes into the cladding. The ray then crosses to the other side of the core and, because the fiber is more or less straight , the ray will meet the cladding on the other side at an angle which again causes TIR. The ray is then reflected back across the core again and the same thing happens. In this way the light zig zags its way along the fiber. This means that the light will be transmitted to the end of the fiber. In reality the light which enters the fiber is a focused beam, consisting of many millions of "rays" behaving in a similar way. They all zig zag along the core of the fiber, crossing over each other, and filling up the core with light. A pulse of light traveling along the core of the fiber is really a bundle of these rays.
What happened to the ray of light when it entered the water?
if the ray of light enters the water from air,refraction takes place and the ray of light will bend towards the normal due to higher optical density.

What is the characteristic difference between a beam of light and a ray of light?
A beam of light is a broad, focused stream of light, while a ray of light is a narrow, straight path that light travels in. The beam carries more energy and can illuminate a larger area, while a ray is a simplified representation of how light propagates in a specific direction.
Why ray does not refract when it passes through optical centre?
When light passes through the optical center of a lens, it does not refract because the optical center is the point from which light rays are believed to pass undeviated. This means that the angles of incidence and refraction are both zero, resulting in no bending of the light ray.
