It is desired to obtain a diffraction pattern for electrons using a diffraction grating with lines separated by 10 nm.The mass of an electron is 9.11 × 10^-³¹ kg.
-Suppose it is desired to observe diffraction effects for a beam of electromagnetic radiation using the same grating.Roughly,what is the required energy of the individual photons in the beam?

Question

Quizplus · Accepted Answer

The energy of photons required to observe diffraction effects is related to their wavelength, which should be comparable to the grating spacing (10 nm). Using the energy-wavelength relation for photons (E = hc/λ), the energy is approximately 10² eV.
