**How to measure the refractive index of light without using a spectrometer? - index.of mature jpg**

I was doing a physics project to see with the help of a spectrometer, the impact on the index of refraction of light, changing the light source or the concentration of the solution to the Prism / type of solution on the prism. Other possibilities that I do this research? except through the prism spectrometer ...

How do you think they did before they invented the spectrometer? ;-)

Ok, you have to go 2 ways you can.

Or use the Brewster angle. For this you need a polarizer and polarization of the light horizontally. When it reaches the glass, there will be a certain angle to go in the light of all in the glass, without reflection. that the angle is determined by tan (theta) = given N1/N2, where n is the refractive index.

You can then use the total reflection. When a light beam tried by a medium to high rate low pull through, there's a perspective reflected completely from the. I'm not sure what is the formula, but I think it is sin (theta) = N2/N1

Hope it helps! Spectrometer and cut back to the basics:-P

If the material, which by the light refractive index is not his own light. A spectrometer allows researchers at an angle to the line of zero degrees to find the light, the prisms, gratings, etc. Another way to find this position, the image on a screen of a known distance other project . Pythagoras theorm then you can not simply the inverse sin OPP / HYP to find the angle. Now you can know the angle of refraction, n order to find the use of the angle of incidence and Snell, the refractive index of glass. n = sini / t. sin Be careful, as a prism angle is the angle to normal as the light from a glass into the air. (Inside surface of the prism that will come to light)

I hope that helps.

Light does not have a refractive index media by EO

the following formula:

Sin of the angle of incidence of the sin of the angle of refraction divided
