WebThe refractive index of the medium can be calculated using the formula: n = c/v. Substituting the values in the equation, we get. n = 3 × 10 8 m/s/1.5 × 10 8 m/s = 2. The refractive index of the medium is 2. The speed of light in an unknown medium is 1.76 × 10 8 m/s. Calculate the refractive index of the medium. WebAll-polymer multilayer hollow core photonic fiber preforms were fabricated using consecutive deposition from a solvent phase of two polymers with high and low refractive indices (RI).
WebThe index of refraction value of a material is a number that indicates the number of times slower that a light wave would be in that material than it is in a vacuum. A vacuum is given an n value of 1.0000. The n values of other materials are found from the following equation: The table below lists index of refraction values for a variety of medium. A high-refractive-index polymer (HRIP) is a polymer that has a refractive index greater than 1.50. Such materials are required for anti-reflective coating and photonic devices such as light emitting diodes (LEDs) and image sensors. The refractive index of a polymer is based on several factors which include polarizability, chain flexibility, molecular geometry and the polymer backbone orientation.
