The energy of photons that would be chosen and the reason.
Answer to Problem 1Q
The energy of the light must be greater than
Explanation of Solution
The diffraction of photons by the nuclei occurs when the wavelength of the light is either equal to or less than the size of the nuclei.
Write the expression for the energy of the photon.
Here,
Substitute
From above, it is clear that the energy of the photons must be greater than
Conclusion:
Therefore, the energy of the light must be greater than
