Understanding the Relationship

* Speed of light in a vacuum (c): This is a fundamental constant, approximately 299,792,458 meters per second (m/s).

* Refractive index (n): This represents how much slower light travels in a medium compared to a vacuum.

* Speed of light in a medium (v): This is the speed we want to find.

The Formula

The relationship between these values is:

n = c / v

Solving for the Speed of Light in Carbon Disulfide (v)

1. Rearrange the formula: v = c / n

2. Substitute the values: v = (299,792,458 m/s) / 1.628

3. Calculate: v ≈ 184,073,000 m/s

Therefore, the speed of light in carbon disulfide is approximately 184,073,000 meters per second.
