State de Broglie hypothesis.

State de Broglie's hypothesis and write down the expression for the wavelength of matter waves.

What is de Broglie hypothesis?

Assertion : If the wavelength lamda of photon and de Broglie wavelength of electron are same , their energy is also same. Reason : Momentum of both the particles is same by de Broglie hypothesis.

On the basis of the de Broglie hypothesis, obtain the expression for the de Broglie wavelength associated with an electron accelerated from rest through a p.d. V.

What is de Broglie hypothesis? What conclusion can be drawn from Davisson and Germer’s experiment?

Show that de-Broglie hypothesis of matter wave supports the Bohr's concept of stationary orbit.
