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.
