Calculate the refractive index of a liquid with respect to air applying Snell's law (Use Geometric construction) Answer is 1.19Show all the steps​

Answer»

tion:This was a question in our school prelim PAPER too. ICSE 10th. In air you will SEE that they have not provided the angle of incidence you have to find itAngle of Incidence = 90 - 30 degree = 60 degrees why?because the normal  is perpendicular to plane.Now they have given the angle of refraction = 45 degrees Snell's LAW states that the ratio of the sines of the angles of incidence and refraction of a wave are constant when it passes between two given media.therefore, μ = sin60 = sin45 = On solving you will get, = 1.19 approx.
