A light wave of frequency `4xx10^(14)"Hz"` and a wavelength of `5xx10^(-7)m` passes through a medium. Estimate the refracetive index of the medium.

Explanation

`upsilon = 4xx10^(14)Hz`
`lambda=5xx10^(-7)m`
`v=upsilon lambda=4xx10^(14)xx5xx10^(-7)=20xx10^(7)`
`=2xx10^(8)m//s`
we know that `C=3xx10^(8)m//s`
`mu=(C)/(v)`
`mu=(3xx10^(8))/(2xx10^(8))`
`mu=(3)/(2)=1.5`
