Refraction Glass Math

V c mu v c μ.

Refraction glass math. Here c is speed of light and. Light refracts more when moving through glass than when moving through water. However all the colors of light do. When light passes into another material like glass or water refraction causes it to bend.

V is the speed of light in the medium. Sunlight actually consists of all the colors of light mixed together. Air 1 atmosphere pressure 0 degrees c 1 00029. N c v displaystyle n frac c v.

Now applying snell s law when the light ray is leaving the glass slab through another surface sin i 2 sin r 2 1 n sin r 2 sin i 2 n refractive index of glass sin i 1 sin r 1 sin r 2 sin i 2. In optics therefore the law of refraction is typically written as. When the arrow is moved to a particular distance behind the glass it looks like it reversed itself. C is the speed of light in vacuum and.

They are however directly related through the speed of light in vacuum c as. This bending of light is called refraction. We call the substances that light can move through mediums. Light refracts at different angles depending on the density of the medium.

A bigger refractive index means a lower speed. Water glass and air are mediums. This is true because glass is denser than water. The index of refraction is seen because the equation by which the wavelength and velocity of light ray changes with refraction is v c μ.

Thus the quality of glass is determined with the help of its refractive index. When light passes from one material to another it can bend or refract. Water 20 degrees c 1 33. N 1 sin θ 1 n 2 sin θ 2 displaystyle n 1 sin theta 1 n 2 sin theta 2.

The ratio of the speed in a vacuum to speed in the medium is called the refractive index or index of refraction. In the experiment that you just completed light traveled from the air through the glass through the water through the back of the glass and then back through the air before hitting the arrow.
