The Refractive Index

Here, the boundary simply reflects the ray which is unable to escape from the perspex medium at all. AN mismatch loss is typically only a concern with multimode optical fiber. However, a loss will not occur if the AN of the transmitting optical fiber is less than the AN receiving optical fiber.

Each change in the refractive index causes a certain amount of light to be reflected and therefore lost. Andrew Olivier,p. A quantitative were introduced in the s.

Turn the knob so that the line separating the dark and light areas is at the corsairs. Lateral misalignment loss occurs when light from the core of the transmitting optical fiber enters the cladding of the receiving optical fiber, creating a loss.

Furthermore, prisms do not suffer from complications arising from overlapping spectral orders, which all gratings have.

Essay Example: Refractive index

The consequences of the small angles are more serious than the bigger angles. Before Isaac Newton, it was believed that white light was colorless, and that the prism itself produced the color.

However, a loss will not occur if the AN of the transmitting optical fiber is less than the AN receiving optical fiber. Water normally forms a bubble shape when adhered to materials such as glass.

The method has some weaknesses. Cladding noncircular may cause loss when it causes part of the core of the transmitting optical fiber to align with the cladding of the receiving optical fiber.

This makes a prism a useful substitute for a mirror in some situations. An A4 size sheet of plain paper 7. Because the AN of a multimode optical fiber is greater than the AN of a single-mode optical fiber, multimode splices tolerate angular misalignment better than single-mode splices.

The relationship between refractive index and temperature is due to the decrease in density and dielectric constant of the medium. AN mismatch loss is typically only a concern with multimode optical fiber.

A loss occurs when light at the outer edge of the transmitting optical fiber core falls outside the diameter of the receiving optical fiber core.

The Refractive Index Essay The refractive index Aim: The aim of this experiment is to find the refractive index of a glass prism. In this experiment, the independent variable is the angle of incidence, and the dependent variable is the angle of refraction.

The refractive index of many materials (such as glass) varies with the wavelength or color of the light used, a phenomenon known as dispersion. This causes light of different colors to be refracted differently and to leave the prism at different angles, creating an effect similar to a rainbow.

Once the refractive index and density is obtained, the Lorents-Lorenz equation can be used to determine the specific refraction of each substance: where n is the refractive index, N is the number of molecules per unit volume and alpha is the polarizability.

The first is through Freeness reflection, which takes place when light passes from the higher refractive index of the core in the transmitting optical fiber into the lower refractive index of the air, and then back into the core of the receiving optical fiber.

Once the refractive index and density is obtained, the Lorents-Lorenz equation can be used to determine the specific refraction of each substance: where n is the refractive index, N is the number of molecules per unit volume and alpha is the polarizability.

Once the refractive index of a certain medium is known, the angle of refraction can be calculated if the angle of incidence and known and vice versa.

The denser the medium, the larger the refractive index.
