Question

derive an expression for de broglie wavelength​

Answer 1

Answer:

Deriving the de Broglie WavelengthE=mc2.E=hνmc2=hνmv2=hνmv2=hvλλ=hvmv2=hmv.

Answer 2

$\huge\mathcal\colorbox{yellow}{{\color{blue}{AnSwEr~↓~↓~}}}$Formulas Used: E=mc2, E=hν and ν=vλ. ... ⇒λ=hp where λ denotes de Broglie wavelength of matter waves, h is planck's constant (h=6.62607×10−34 Joule-sec) and p denotes the momentum of the matter wave. The above equation represents the required expression for de Broglie wavelength of matter waves.$\huge{\boxed{\red{hope\:it\:help\:you}}}$
