Light travels from a rarer medium 1 to a denser medium 2. The angle of incidence and refraction are respectively `45^(@)` and `30^(@)`. Calculate the refractive index of second medium with respect to the first medium.

Explanation

To calculate the refractive index of the second medium with respect to the first medium, we can use Snell's Law, which states:

\[ n_1 \sin i = n_2 \sin r \]

where:
- \( n_1 \) is the refractive index of the first medium,
- \( n_2 \) is the refractive index of the second medium,
- \( i \) is the angle of incidence,
