Answer 2

@iGreen.

Answer 3

Speed of light is fastest in vacuum, which is very similar to the speed in air.
Anything else will \(slow\) the velocity down by a factor equal to the refractive index.
So
\(c=3\times10^8 m/s\)
and
\(\mu=2.4\)
so velocity of light in diamond = ?

Answer 4

1.24 x 10^8

Answer 5

Correct if you used \(\mu=2.42\), otherwise 1.25\(\times10^8\) m/s
