Question

If the kinetic energy of a moving particle of mass is e,then the de broglie wavelength lamda is

Answer 1

heya mate !!!!

E=h. frequency

E=h.f. -----------------------(1 )

________________________

acc to Einstein,,

E=mc^2. --------------(2)

________________________

frequency =c/wavelength(lamda)

E=h.c/wavelength

equating both eq.

h. /wavelength =mc

wavelength =h/mc

hope it helps u dear ❤
