Question

Two particles with equal de Broglie wavelength can have equal speed, equal kinetic energy, equal amount of movement and equal frequency?

Answer 1

Two particles with equal de Broglie wavelength can have equal speed

wavelength(λ) = λ

frequency(v) = v

c = wavelength(λ) * frequency(v) here c is speed of light

for first particle

v 1= c/λ

for second particle

v2 = c/λ

v1=v2

and

E = hv here h is constant

E1=E2

also

E=1/2mv² here v is velocity

energy is equal and let mass is same then,

also velocity is equal

and,

E=pc here p is moment

energy is equal and c is constant

so, moment is eaual
