What is the index of refraction of this substance?

Here's what I've done so far:

(3.0*10^8 m/s)(0.79) because its 79%.

In water, the n=1.003.

I'm not sure where to go from there.

Any help would be greatly appreciated!

Thanks in advance.

No, that'sThe speed of light in a certain substance is 79.0% of its value in water.

correction:

n=1.33

and the speed of light in water (3x10^8)/(1.33)=2.25x10^8

n=1.33

and the speed of light in water (3x10^8)/(1.33)=2.25x10^8

Hope that's enough.The speed of light in a certain substance is 79.0% of its value in water.

Since 79%, mulitplying (2.26x10^8)(0.79)= 1.78x10^8.

Correct?

Correct?
