Question

the refractive index of rock salt with respect to water is 1.17. What will be the refractive index of water with respect to rock salt

Answer 1

1.17

Step-by-step explanation:

Given that,

The refractive index of rock salt with respect to water is 1.17.

We need to find the refractive index of water with respect to rock salt.

We know that,

Refractive index = (speed of light in air or vaccum)/( speed of light in that medium)

Refractive index of rock salt with respect to ice = (speed of light in ice)/(speed of light in rock salt)

The speed of light in ice = c/1.31

The speed of light in rock salt = c/1.54

Required refractive index,

`\mu=(1.54)/(1.31)\\\\=1.17`

So, the refractive index of water with respect to rock salt is equal to 1.17.
