Use the de Broglie's Wave Equation to find the wavelength of an electron moving at 4.5 x 10^6 m/s. Please show your work. Note: h= Plank's constant (6.62607 x 10^-34 J s)

λ = 1.61x10⁻¹⁰ m

Explanation:

Broglie's wave equation is the following:

Where:

λ: is the wavelength of the electron

h: is the Plank constant = 6.62x10⁻³⁴ J.s

m: is the mass of the electron = 9.11x10⁻³¹ kg

v: is the speed of the electron = 4.5x10⁶ m/s

The wavelength of the electron is:

Therefore, the wavelength of an electron moving at 4.5 x 10⁶ m/s is 1.61x10⁻¹⁰ m.

I hope it helps you!
