Satellite in Elliptical orbit

When finding the period of a satellite orbiting the earth we equate the centripetal force to the gravitational force $$frac{mv^2}{r} = frac{-GMm}{r^2}$$If I understood well the $r$ cancels into...

Why has $evB$ been equated to $mv^2/R$ here?

When $24.8 keV$ x-rays strike a material, the photoelectrons emitted from K shell are observed to move in a circle of radius $23mm$ in a magnetic field of...

Symmetric potential well different solutions

I have solved $H|psirangle=E_{n}|psirangle$ with $V(x)=0$ from $-a<x<a$ and $infty$ otherwise.If I propose a solution of the form $psi(x)=A_{n}e^{ikx}+B_{n}e^{-ikx}$ I arrive to the solution...

Is the scalar magnetic potential continuous?

If we have two current-free spaces and separated by a surface current, we can solve the magnetic problem by solving two magnetic scalar potentials and then using matching conditions. My...

What is the detector in the double slit experiment and how does it work?

Is the detector a passive device or is it just a fictional mathematical probe.I think the detector is somehow consuming the energy responsible for the wave nature of the...

What does CMBR has to do with quantum fluctuations during rapid inflation?

I know the almost homogeneous of cosmic microwave background radiation is claimed to be caused by the rapid expansion of quantum fluctuations in the early universe, but what does density...

Do all sounds that have a pitch have a fundamental frequency?

My current understanding is that if a sound has a pitch it must be periodic, i.e. it is composed of sound waves that have frequencies. So I assume that means...
