How does salt effect the refraction index of water
2.045 Words / ~13 pages Copenhagen Nørre Mi­ni Ex­ten­ded Es­say what is the ef­fect of salt on the re­frac­ti­ve in­dex of the wa­ter. Phy­sics Mi­ni Ex­ten­ded Es­say Ta­ble of Con­tent In­tro­duc­tion: This Mi­ni Ex­ten­ded Es­say is an in­ves­ti­ga­ti­on of how the sa­li­ni­ty ef­fects the re­frac­ti­ve in­dex of wa­ter when a spe­ci­fic con­cen­tra­ti­on of salt is dis­sol­ved in it. To pro­ve the theo­ry that sa­li­ni­ty in­fluen­ces the re­frac­ti­ve in­dex of the wa­ter I car­ri­ed out this ex­pe­ri­ment by using a dif­frac­tion gra­ting. The re­frac­ti­ve in­dex, which is al­so cal­led the in­dex of re­frac­tion, is used to me­a­su­re the ben­ding of a light ray, when it tra­vels from one me­di­um in­to an­o­ther me­di­um. In my ex­pe­ri­ment, I used it to me­a­su­re the re­frac­ti­ve in­dex of nor­mal tap wa­ter first and then salt dis­sol­ved in wa­ter. I did this to see what, other than salt, ef­fects the re­frac­ti­ve in­dex of the wa­ter. And to find the dif­fe­rence in…[show more]

Man­kind will al­ways be loo­king for the re­ason, on why hu­mans, or our pla­net and the who­le uni­ver­se now is li­ke, and now we can ob­ser­ve it be­cau­se hu­mans are very in­qui­si­ti­ve and want to know ever­y­thing. The­re are ma­ny theo­ries for the big bang. Phy­si­cists do not even know if the Big Bang was re­al­ly the be­gin­ning of our uni­ver­se or just an ear­ly pe­ri­od in the uni­ver­se, but in this self-stu­dy, I’ll ex­plain the lea­ding con­cept from the…[show more]
