Calculating wavelength of an electron

[Toru Fiberesima 1L]

When you know the velocity of an electron, how do you then calculate the wavelength?
Thanks

You could use De Broglie's equation: lambda=h/mV, where h is Planck's constant, m is the mass of the electron (which is a constant that would be given to you or you could just look it up) in kg, and V is the velocity in m/s.

When you know velocity of an electron and need to know wavelength use De Broglie's equation. lambda= h/mv

[Molly Oakes 1A]

You know velocity and I believe the mass of an electron is a constant. Therefore, you have mass, velocity, and Planck's, so you can use De Broglie's equation.

In order to calculate the wavelength you will use the equation λ=h/mv
