Calculate the wavelength of a beta particle (electron) that has an energy of 4.35 × 104 eV

2. Relevant equations

E = hf

λ = h/mv

V = W/q

eV = .5mv^2

3. The attempt at a solution

I can't figure out how to get electron volts into a form of energy that I'm familiar with in an equation. I tried

eV = .5mv^2 , but that gave me a speed above the speed of light.

I also tried using E = hf, but that also gave me a ridiculous number.
