Answer:
Explanation:
The de brogllie wavelength is given as
λ = h/mv
where
λ is the de broglie wavelenth
h is the plank constant given as 6.62 × 10-34 m² kg / s
m is the mass of the particle =9.11 x 10⁻³¹ kg
v is the velocity with which the particle moves = 5230 km/s. which as to be converted to m/s by multiplying it by 1000 to give 5230000m/s
hence
λ = 6.62 × 10-34 / 5230000 × 9.11 x 10⁻³¹ =
1.39 ×10^{-10}m
but since the answer must be in nm , we multiply 1.39 ×10^{-10}m by 10^{9}
then we get 0.139nm
