what is the de Broglie wavelength of an electron traveling at 2.00x10^6 m s -1?
we have to use
λ = h / mv
where λ = de Broglie wavelength need to calculate
m = mass of the electron = 9.1×10−31 kg
v = velocity 2.00x10^6 m s -1
h = pank constant = 6.62607 x 10-34 J s
put all these in above equation
λ = 6.62607 x 10-34 / 9.1×10−31 x 2.00 x 106
= 3.642 x 10-10 m
