WebbOil Immersion and Refractive Index. One way of increasing the optical resolving power of the microscope is to use immersion liquids between the front lens of the objective and the cover slip. Most objectives in the magnification range between 60x and 100x (and higher) are designed for use with immersion oil. Good results have been obtained with ... WebbMeasurement of refractive index of water and oil. 1)with water between the convex lens and the plane mirror: 2) With oil between the convex lens and plane mirror. Results. The refractive index of water is µ1 = 1.0831. The refractive index of oil is µ2 = 1.2886. Precautions. 1.The plane mirror should be clean and fully shining surface.

WebbThe Refractive Index - n - of a medium is a measure for how much the velocity of light is reduced inside the medium. The velocity of light in a medium can be expressed as. v = c / n (1) where. v = velocity of light in the medium (m/s, ft/s) c = speed of light in air or vacuum - approximately 3 108 m/s (or 299792458 m/s) n = refractive index. WebbTo find refractive indices of water and turpentine oil using a plane mirror, a equiconvex lens (made from a glass of known refractive index) and an adjustable object needle. … WebbHow it works: Snell's law tells us that refraction depends, among other things, on the ratio of the indices of refraction of the incident and refracting media. The ratio for a glass lens in air is 1.5. When the lens is immersed in water, the ratio becomes 1.5/1.33 = 1.13, thus greatly diminishing the effect. The lensmaker's formula. edith purer
