A glass cube of side 0.2m contain small air bubble it appears to be at 8cm when viewed through one face and 0.06 viewed from opposite find the actual position of the bubble and what is the refractive index of the glass.

==>Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another

==>This question based on Refrective index of science

==> in question you must mention of unit.may be you studied that in physics units are important thing in physics what is 0.06 in question.it shows m or cm.otherwise whatever answer calculated it will be wrong after perfect unit you put.or changing unit will change answer.
