Speed of light air is `3 xx 10^8 ms^(-1)` and the speed of light in a medium is ` 2 xx 10^8 ms^(-1)` . Find the refractive index of the medium with respect to air.

Explanation

To find the refractive index of a medium with respect to air, we can use the formula for refractive index (μ):

\[ \mu = \frac{c}{v} \]

where:
- \( \mu \) is the refractive index,
