Explain Electron's Speed for Probing Nucleus

[rojasharma]

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?

 

[lavalamp]

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.

 

[rojasharma]

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

 

[lavalamp]

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

 

[rojasharma]

I always thought it was the other way around
