Analyzing results finding refractive indexes one of the most common uses of the refractive index is to compare the value you obtain with values listed in the. Wavelength of light because the velocity of light in air is always greater than that through a liquid, the refractive index is a number greater than 1. In this media-rich lesson plan, students explore the refraction of light at the boundary between materials: they learn about the refractive indices of various materials and measure the index of refraction of plastic or gelatin.
Refractive index (n) the refractive index (n) of a material is the ratio of the speed of light (c) in a vacuum to the velocity of light in the material (c s)the refractive index of a material is always greater than 1. For example, a glass has a refractive index of about 15 this means that light travels at 300,000,000 (speed of light in a vacuum) divided by. Snell's law and index of refraction once the angles are calculated for each material then apply snell's law to find the unknown index of refraction for the material.

Snell's law, reflection, and refraction in order to follow the quickest path through a system, a ray changes direction as it travels from a medium of one refractive index to another medium that has a different refractive index. In optics the refractive index or index of refraction n of a substance is a dimensionless number that describes how light, or other radiation, goes through that medium. Microscopy (this passage was adapted from as light is transmitted through a specimen with a refractive index different from that of the surrounding. With refractive index and density of the medium, specific refraction could be obtained using lorentz-lorenz equation (table 3) finally, the molar composition of water and 2-propanol were calculated and are shown in table 4. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index.
