The phase velocity of ocean waves is √(g λ/ 2 π), where g is the a?celeration of gravity. Find the group velocity of ocean waves. | Numerade

(a) Show that the phase velocity of the de Broglie waves of a particle of mass m and de Broglie wavelength λis given by vp=c √(1 ((m c λ)/(h))^2) (b) Compare the phase and group velocities of an electron whose de Broglie wavelength is exactly 1 ×10^-13  m. | Numerade

Determine the group velocity of waves when the phase velocity varies inversely with the square of the wavelength.
