Question

The de Broglie wavelength of an electron with a velocity of 6.90 × 106 m/s is ________ m. The mass of the electron is 9.11 × 10-28 g.

Answer 1

Answer:

Explanation:

use this equation and solve for wavelength (λ)

λ = h/mv.

where h is plancks constant 6.63 × 10−34 J·s

m = mass of lectron

v = velcoeity of electron
