Answer :
Answer:
Frequency, [tex]f=2.30\times 10^{18}\ Hz[/tex]
Explanation:
Given that,
The wavelength of the x-rays, [tex]\lambda=0.13\ nm=0.13\times 10^{-9}\ m[/tex]
We need to find the frequency of an x-ray. All electromagnetic wave travel with a speed of light. It is given by the formula as :
[tex]c=f\lambda[/tex]
f is the frequency
[tex]f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{0.13\times 10^{-9}}\\\\f=2.30\times 10^{18}\ Hz[/tex]
So, the frequency of an x-ray is [tex]2.30\times 10^{18}\ Hz[/tex]. Hence, this is the required solution.
