Question

The speed of light travels through a material that 1.24x10^8m/S what is the material?

Answer 1

Given

The speed of light through a medium is

`v=1.24*10^8\text{ m/s}`

To find

The type of material

Step-by-step explanation

The velocity through a medium is given by

`v=(c)/(n)`

where c is the speed of light in .

n is the refractive index of the material

Thus,

`\begin{gathered} 1.24*10^8=(3*10^8)/(n) \\ \Rightarrow n=2..419 \end{gathered}`

Thus the refractive index is 2.419

We know diamond has a refractive index of 2.417-2.419

Conclusion

The material is diamond
