The refractive index of lens flint glass is 1.65 and for alcohol, it is 1.36 with respect to air, then the refractive index of the dens flint glass with respect to alcohol is
Refractive index of air, μair = 1;
Refractive index of flint glass w.r.t air, airμglass = 1.65;
Refractive index of alcohol w.r.t air, airμalcohol = 1.36;
Refractive index of flint glass w.r.t alcohol = alcoholμglass = airμglass / airμalcohol =
⇒ alcoholμglass = 1.213
Hence the refractive index of flint glass w.r.t alcohol is 1.213.

Mr. Raghav, grade 6 teacher find that his students do not draw when he draws on the board. Every time he had to turn towards them to see whether they draw and label the diagrams. Arav, one of his student fixed two big convex mirrors at the two sides of the black board. With this Mr. Raghav was able to draw and also supervise his students through the mirror. All the students started doing their work property.
