Please use the de broglie equation to determine the wavelength of an electron moving at 5.7x10^6 m/s
The de Broglie equation is given by:
λ = h / p
Where:
λ = wavelength
h = Planck's constant (6.626 x 10^-34 Js)
p = momentum
To find the wavelength of an electron moving at 5.7x10^6 m/s, we need to determine the momentum first. The momentum of an electron can be calculated using the equation:
p = m * v
Where:
m = mass of the electron (9.10938356 x 10^-31 kg)
v = velocity of the electron (5.7x10^6 m/s)
Substituting the values into the equation, we can calculate the momentum of the electron:
p = (9.10938356 x 10^-31 kg) * (5.7x10^6 m/s)
= 5.2000920132 x 10^-24 kg m/s
Now, we can use the de Broglie equation to find the wavelength:
λ = (6.626 x 10^-34 Js) / (5.2000920132 x 10^-24 kg m/s)
≈ 1.273 x 10^-10 m
Therefore, the wavelength of the electron moving at 5.7x10^6 m/s is approximately 1.273 x 10^-10 meters.
