What are de Broglie waves? Show that the wavelength of the electromagnetic radiation is equal to the de Broglie wavelength of its quantum (photon).
Marking-scheme solution
Defining the de-Broglie wave.
Showing the wavelength of electromagnetic radiation equal to de-Broglie
\[\therefore \lambda_{\text {rad }}=\lambda_{p}
\]
