The figure depicts a simplistic
optical fiber: a plastic core (n1 = 1.54) is surrounded by a
plastic sheath (n2 = 1.46). A light ray is incident on one end of
the fiber at angle ?. The rays is to undergo total internal
reflection at point A, where it encounters the core-sheath
boundary. (Thus there is no loss of light through that boundary.)
What is the maximum value of ? that allows total internal
reflection at A?

An optical fiber consisting of a core made of glass (n = 1.667) surrounded by a crown glass lining (n = 1.523). A ray of light in the air enters the fiber at an angle φ 1 with respect to the normal one. What is φ 1 if this light also affects the core cladding interface at an angle that barely exceeds the critical angle?

Question 1: The core of an optical fiber is made from flint glass (nfint = 1.667) and is surrounded by cladding made from crown glass (ncrown = 1.523). A light ray enters the fiber at an angle of incidence of 0. What is this value of O, if the light strikes the core-cladding interface at the critical angle? Cladding Core Air

1. (a) A laser beam enters an optical fiber with an incident angle of 6max as shown in Figure 1. Its corresponding refracted light is subsequently incident on the boundary between the core and the cladding whose refractive indices are ni and n2, respectively.

Question 19 of 31 > The index of refraction for a certain type of glass is 1.637 for blue light and 1.607 for red light. A beam of white light (one that contains all colors) enters a plate of glass from the air, r1, at an incidence angle of 37.05.

(2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...
