Web1061 Words. 3 Pages. Refraction is the bending of a wave as it passes at an angle from one medium to another. One common example of refraction of light waves is the broken pencil effect that can be observed when a pencil is placed in a glass of water. The pencil seems to be "broken" at the surface of the water as the light waves go from the air ... WebAnd we know what the refraction index for air and for water is, and then we just have to solve for theta 2. So let's just do that. The refraction index for air is this number right over here, 1.00029. So it's going to be, there's three 0's, 1.00029 times the sine of 35 degrees, is going to be equal to the refraction index for water, which is 1.33.

The refractive index is an important property of the components of any optical instrument. It determines the focusing power of lenses, the dispersive power of prisms, the reflectivity of lens coatings, and the light-guiding nature of optical fiber. Since the refractive index is a fundamental physical property of a substance, it is often used to identify a particular substance, confirm its purity, or measure its concentration.
