The French physicist, de Broglie, in 1924 proposed that matter, like radiation, should also ? exhibit dual behaviour i.e., both particle and wavelike properties. This means that just as the photon has momentum as well as wavelength, electrons should also have momentum as well ? as wavelength. De Broglie gave a relation between wavelength and momentum ?
Q1.What is de Broglie?s relation? ?
Q2.Why are de Broglie?s wavelength associated with a moving football is not visible?
Dear student,
Ans-1 The de Broglie equation is:
λ = h/mv
where,
λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v.
p(momentum) = mv
λ = h/p
Ans-2 De Broglie's wavelength is not visible with a moving football because of its large mass , the wavelength associated is very small. So, its wave nature is not visible.
Regards
