Show that the wavelength of electromagnetic radiation is equal to the de-Broglie wavelength of its quantum (Photon).

What is the de Broglie wavelength

Wavelength of electromagnetic radiation is doubled, what will happen to energy of photon?

The kinetic energy of an electrons is equal to the energy of photons. Show that de-Broglie wavelength of this electrons is less than the wavelength associated with a photon.

If photon and an electron have same de-Brogile wavelength then.

If the velocity of electron in bohr's is 3.5(10*6)ms-1, calculate the de broglie wavelength associated with it.

Draw a graph showing variation of de-Broglie wavelength with the momentum of an electron?
