Answer:
[tex]E=1.32\times 10^{-17}\ J[/tex]
Explanation:
Given that,
The wavelength of x ray, [tex]\lambda=15\ nm=15\times 10^{-9}\ m[/tex]
We need to find the energy if a photon on the x-rays. The formula for the energy of the photon is given by :
[tex]E=\dfrac{hc}{\lambda}[/tex]
[tex]E=\dfrac{6.63\times 10^{-34}\times 3\times 10^8}{15\times 10^{-9}}[/tex]
[tex]E=1.32\times 10^{-17}\ J[/tex]
So, the energy of a photon of the X-rays is [tex]1.32\times 10^{-17}\ J[/tex]. Hence, this is the required solution.
