Water index of refraction
The science behind the water refraction experiment: Refraction is the bending of light. In this case, light traveled from the air, through the front of the glass jar, through the water, through the back of the glass jar, and then back through the air, before hitting the picture. Whenever light passes from one medium into another, it refracts. The index of refraction, or refractive index, is a measure of how fast light rays travel through a given medium. Alternatively, it could be said that refractive index is the measure of the bending of a light ray when passing from one medium to another. As you can imagine, the index of refraction for every medium is different. For instance, the refractive index of air is usually considered to be 1.0003, while for water, it’s 1.333 and so on. The index of refraction is also a function of water pressure, but the dependence is quite weak because of the relative incompressibility of water. In fact, over the normal ranges of temperatures (0-30 C), the approximate increase in n(w) is 0.000016 when the water pressure increases by one atmosphere. Refractive index of water Most people would assume that the refractive index of water is known to a high degree of accuracy. However, as shown in Fig. 1, the published literature reveals significant differences in the values of refractive index of water for a given wavelength. The index of refraction for a given medium is a unitless number n where n = c/v, where c is the speed of light in a vacuum and v is the speed of light in the medium. The slower light travels in a medium, the higher that medium's index of refraction will be. The index of refraction for 80% sugar solution is known to be about 1.5, while water is 1.33. The index of refraction (n) is a number with no units. Fig4: The the sugar solution is more concentrated at the bottom of the aquarium, which creates a gradient of the indices of refraction. The index of refraction for the ordinary ray is constant and is independent of direction. The index of refraction for the extraordinary ray is a continuous function of direction. The index of refraction for the ordinary ray is independent of direction. The two indices of refraction are equal only in the direction of an optic axis.

Refractive index is defined as the ratio of the speed of light in a vacuum to that in a given medium. For water and air, the ratio is very nearly 4/3; for glass and air, it is close to 3/2. ( It's just a coincidence that the refractive indices of these common materials are so In other words, when light comes in contact with certain surfaces, like water or glass, the light will get slightly bent because Mathematically, the index of refraction is the ratio of the speed of light through a vacuum The refractive index can also be calculated by measuring the angle of In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength—thus, the imaginary part is sometimes called the extinction coefficient.
