# Speed of Light Calculation in Material with Index of Refraction 1.7

## What is the speed of light in a material with an index of refraction of 1.7?

What formula can be used to calculate the speed of light in a material with a given index of refraction?

## Speed of Light in Material with Index of Refraction 1.7

The speed of light in a material with an index of refraction of 1.7 is approximately 177 million meters per second.

When dealing with the speed of light in a material with a specific index of refraction, we can use the formula:

**v = c / n**

Where:

**v** = speed of light in the material

**c** = speed of light in a vacuum (299,792,458 m/s)

**n** = index of refraction

Given that the index of refraction (n) is 1.7, we can substitute the values into the formula:

**v = 299,792,458 m/s / 1.7**

By solving this equation, we find that the speed of light in the material with an index of refraction of 1.7 is approximately 177 million meters per second.
