*Q.*The de-Broglie wavelength of an electron moving with a velocity of is equal to that of a photon.The ratio of kinetic energy of the electron to that of the photon**:**

Solution

Matter waves are a central part of the theory of quantum mechanics, being an example of wave–particle duality. All matter can exhibit wave-like behavior. For example, a beam of electrons can be diffracted just like a beam of light or a water wave.

The

**de Broglie equation**is an equation used to describe the wave properties of matter, specifically, the wave nature of the electron:

**λ = h/mv,**where λ is wavelength, h is

**Planck's constant**, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.
