Calculate the de brogile wavelength of an electron traveling at 2.0

answer:

explanation: before taking the qutetion we should know about what is de brogile equation and why we use it. we know that waves have characteristics of particals also particals have characteristics of waves for that de brogile equation is introduced

λ = h/ (mv)

λ = de brogile wave length

h - planks constant

m - mass

v - velocity

λ =6.62×10-34 / (9.31×10-31×2)

λ = 3.55×10-4 m

god i hope this !
