Use the de Broglie equation to explain which is better probe of the contents of the nucleus--a fast-moving electron, or a slow-moving electron. Can someone simplify what the qestion is asking for?

Compare the wavelength of higher and lower energy electrons. Now consider which would be better to probe the very small nuclei of elements. That's it really, which is best.

so the faster it is ...shorter the wavelength ...the faster moving electron will be helpful to probe the nucleus...

Indeed, the smaller the wavelength, the smaller the features it can resolve.

I always thought it was the other way around
