What are de-Brogli Waves ? How does the de-Broglie wavelength vary with momentum of moving particle ?

What is the de Broglie wavelength

What is de-Broglie wave?

What are de-broglie waves? Establish the de-Broglie wavelength equation.

For the de-Broglie wavelength of 10^(-17) metre, momentum of a particle will be

The de Broglie wavelength associated with a material particle is:

For a moving electron, the de Broglie wavelength is 1 Å . What will be the de Broglie wavelength if (i) the momentum of electron be doubled, (ii) the kinetic energy of the electron be doubled?
