Beta particle interaction with matter

AI Thread Summary
Beta particles, which are fast-moving electrons emitted from atomic nuclei, can pass through human tissue, such as the palm of a hand, due to the atomic structure of matter. Atoms consist mostly of empty space, with a dense nucleus surrounded by a sparse cloud of electrons, allowing beta particles to navigate through without significant interaction. The limited interaction occurs because beta particles can pass by the electrons in atoms without colliding. This phenomenon relates to quantum physics, where the behavior of particles differs from classical expectations. Understanding this interaction highlights the nature of matter at the atomic level.

A beta particle consists of a fast moving electron emitted from the nucleus of an atom. Beta particles can pass through the palm of a human hand.

My question is .. Being a particle how can it pass through the palm of a hand? I still haven't done quantum Physics but I suspect that it has something to do with it.

What would prevent a beta particle from passing through the palm of a hand?

my reasoning is that waves can make it through somehow ... but particles are stopped after colliding with other particles.

Your hand is made of molecules that are made of atoms. And atoms are very small nuclei with a sparse cloud of electrons around it. Almost all of an atom, and so almost all of your hand is empty space.

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
