      the deBroglie wavelength shows that particles act as both particles and waves. Its dependent on the mass and speed only, so if a particle is moving very fast it will have a wavelength. Even a moving car has a wavelength but because the speed is so small compared to the speed of an electron (speed of light) we can never detect it

      de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle and is also called de Broglie wavelength…..

      So the problem here is atoms act like particles (that has mass and momentum )and also like light (has frequency and wavelenght) at the same time and de broglie showed the relations between these properties…
