Question

aubIf any is refractive index of medium A with respect to medium B, then which of the following relations is correct for refractive index ?​

Answer 1

Answer:

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of incidence to the sine of the angle of refraction; i.e., n = sin i / sin r. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

Answer 2

Answer:

The equation for the refractive index is $n=\frac{c}{v}$$=\frac{sini}{sinr}$

Explanation:

The index of refraction, or in other words the refractive index(RI) is often stated as the measure of the change or the bending of the light ray whenever it is passing from one certain medium into another one. If we assume that ∠i is the incidence angle of a ray in vacuum medium and ∠r is taken to be the angle of refraction, then in that case RI is usually abbreviated as (n) is referred as the ratio of the sine of the incidence angle to the sine of the angle of refraction the equation of which is given below:

$n = \frac{sin i}{sin r}$

Refractive index or the RI is also taken equal to the velocity or speed of light abbreviated as c of a given certain wavelength in empty or vacuum space divided by its speed or velocity abbreviated as v in a substance, which is given as:

$n = \frac{c}{v}$
