What is the speed of gravity?

The speed of gravity is one of the unresolved physics problems. Although for the first time Newton has introduced force into mathematical equations of physics, it was discussed long time ago....

What is the speed of light in a vacuum really? And who measured it?

Galileo was the first scientist who has tried to measure the speed of light but failed. Although the Galileo 's method to determine the speed of light was very primitive, it was precisely a...

How a light source emits (or absorbs) a photon? Where do photons go in absorption?

In quantum mechanics, "electrons can absorb energy from external sources, such as lasers, arc-discharge lamps, and tungsten-halogen bulbs, and be promoted to higher energy levels. This tutorial...

What are quantum fields made up of really?

There is still no consensus on whether the fields are composed of particles or no. For examples: Art Hobson, There are no particles, there are only fields, American Journal of Physics 81, 211...

Is it possible to conclude from the de Broglie wavelength that all particles even photon have masses?

In 1924 de Broglie assumed that for particles the same relations are valid as for the photon: E=hf and E=pc Where E and p are the energy and momentum of the...

What is the effect of gravity on the light?

A pulse of light carries energy and momentum, and it is deflected by the gravitational field of a massive body. Then, according to Newton's 'actio equals reactio', it is also a source of a...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

How Relativistic effects is one reason for lanthanide contraction?

The Lanthanide contraction which is the decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, is due to poor shielding of the 4f...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
