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
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
