Given
The speed of light through a medium is
To find
The type of material
Explanation
The velocity through a medium is given by
where c is the speed of light in .
n is the refractive index of the material
Thus,
Thus the refractive index is 2.419
We know diamond has a refractive index of 2.417-2.419
Conclusion
The material is diamond
