The distance travelled by a ray of light in two media, in the same time are in the ratio 2 : 3. The ratio of refractive index of the first medium to second medium is

A ray of light is travelling from medium A to medium B . The refractive index of the medium B does not depend upon

Define the refraction index of the second medium with respect to the first medium.

A ray of light is incident obliquely at a boundary separating two media . What is its behaviour if (1) the refractive index of the second medium is grater than that of the first medium (2) the refractive index of the first medium is greater that that of the second medium ? Draw the corresponding neat and labelled diagrams.

A ray of light travelling in air is incident at 45^(@) on a medium of refractive index sqrt(2) . The angle of refractive in the medium is

Figure shows a ray of light as it travels from medium A to medium B. Refractive index of the medium B relative to medium A is
