This is correct for mechanical waves, but does not apply to light or electromagnetic radiation. Let me explain why. … This allows us to draw a few conclusions for EM radiation and for subatomic particles: there is no amplification and extinction of waves or their components; there are no waves involved at all it is not …

What is EM radiation You have radiation always and everywhere. It occurs primarily through the relaxation of subatomic particles by means of photon emission. The previously necessary excitation of the …

There are longitudinal waves and transverse waves. The first oscillates in the direction of propagation (sound), the second oscillates perpendicular to it. … See furthermore what are photons, EM radiation and EM waves …

Matter waves are energy transfers without matter transport in the direction of propagation. However, the molecules of the carrier substance are moving. … Only electromagnetic waves in a vacuum suffer no losses. …

There, the ends cause ring-shaped waves again. …

Superposition describes the effect of two waves,… stating that the resultant displacement is equivalent to the vector sum of the individual waves. … Does this mean non-coherent waves cannot interfere, because of how interference is defined? See above. Any two waves interfere. The definition of interference is not limited to coherent waves. …

The story is completely different for electromagnetic waves. Here, the amplitude is associated with the energy of the wave. …

My doubt comes when, for example, we take a metal bar (aka: antenna) and we irradiate it with an EM wave, we know that the changing electric field will move the electrons up an down in the antenna cr …

Normally I always quote from a question and answer it specifically. I find that difficult with your question, but nevertheless let me try to explain. In a pressure wave between two media, the pressure …

In case of electromagnetic waves, the electric field values oscillate with time. … Also, I would like to add that for strings the direction of displacement at nearby points was completely determined by the source point, but for EM waves the direction of electric field at one point does …

If I understand correctly, the intensity of light is proportional to the number of photons hitting a certain area. The intensity of light is proportional to the number of photons and their energy co …

TL;DR An oscillating electron emits photons. These photons have an E and a B field component and their field components converge into each other and propagate with c. (Whoever has something against ph …

Since water waves (from a stone in a pond) always oscillate perpendicular to the horizon, they are always polarised. … For long-wave radio waves, the plane of polarisation is always given for the electrical component of the EM radiation. …

It is possible to polarise EM radiation without using a polarising filter. If you periodically accelerate electrons all in the same direction, you will get polarised radiation, which, however, is osci …

There is an essential difference between EM radiation and sound. Every sound is transmitted by means of the medium (air, water, solid bodies). And, wherever propagating sounds meet, the medium vibrate …
