Explain Electron's Speed for Probing Nucleus

AI Thread Summary
The discussion focuses on using the de Broglie equation to determine whether fast-moving or slow-moving electrons are better for probing atomic nuclei. It highlights that faster electrons have shorter wavelengths, which allows them to resolve smaller features within the nucleus. The consensus is that higher energy electrons are more effective for probing due to their ability to reveal finer details. The conversation clarifies misconceptions about the relationship between electron speed and probing capability. Ultimately, faster-moving electrons are deemed superior for nuclear probing.

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

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
