Refractive index of liquid
17/12/2009 14:21
To find the refractive index of a liquid
Formula = Refractive index =Real depth / Apparent depth.
This experiment is carried out using the method of No parallax.
Parallax = Apparent movement of an object with regard to another object, due to observer motion.
Errors occur here in measuring the distance from the pin to the mirror. ie ruler error.
