In an electrom microscope we wish to study paprticles of diameter about 0.10 µm (about 1000 times the size of a single atom).

What should be the de Broglie wavelength of the electrons?

Through what voltage should the electrons be accelerated to have that de Broglie wavelength?

2. Relevant equations

?

3. The attempt at a solution

I know the equation

wavelength = h / p,

but that doesn't seem to get me anywhere, but that's the only equation for the de Broglie wavelength I know. Therefore, I should look for ways to find p by using the diameter of the particle, but a particle's size shouldn't matter towards its momentum.

So is there are a couple of equations I'm missing, that can get me from the one given quantity of diameter to the wavelength?
