Answer : The frequency of the x-ray is, [tex]0.5996\times 10^{17}Hz[/tex]
Explanation :
Formula used :
[tex]\nu=\frac{c}{\lambda}[/tex]
where,
[tex]\nu[/tex] = frequency of the x-ray = ?
c = speed of light = [tex]2.998\times 10^8m/s[/tex]
[tex]\lambda[/tex] = [tex]5\times 10^{-9}m[/tex]
Now put all the given values in the above formula, we get the frequency of the x-ray.
[tex]\nu=\frac{2.998\times 10^8m/s}{5\times 10^{-9}m}=0.5996\times 10^{17}s^{-1}=0.5996\times 10^{17}Hz[/tex]
Therefore, the frequency of the x-ray is, [tex]0.5996\times 10^{17}Hz[/tex]
