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 …

It’s strange, how Young could conclude from water waves, where constructive and destructive interferences lead to nonstationary intensities at a cross-section (the observation screen) about light waves …

First at all half waves between two walls are easy to evoke. … In standing waves, there is no propagation of energy. With each half-wave, the kinetic energy is converted into tension energy and back. …

If in the wall is a tiny slit the components of the reflected waves left and right the slit dissipate in the direction of the slit (spherical waves in each point according to Huygens description). … Then thinner the wall then less of the waves energy is fading. …

This intensities don't move like the water waves. The light in the fringes does not disappear at some distance in the traveling direction. … So what is the difference between water waves and diffraction of light at an edge? …

This radio waves are electromagnetic radiation, but they are a special case of EM radiation. … So what one could explore in radio waves is the common state of the emitted together photons. …

How about electromagnetic waves? EM waves are EM radiation from an emitter, such as an antenna rod. The most of EM radiation ist from thermal sources and does not show any periodicity. … EM radiation from thermal sources are not EM waves. In both cases - chaotic EM radiation and oscillation radio waves - there is a transportation of energy from the emitter to the receiver. …

Is unpolarised light, different waves with different oscillation directions, all coming from the same source? Yes, if you understand under a source an electric bulb or a laser or a LED. …

The invention of wave generators and the use of antenna roads were the requirements for the production of radio waves. A lot of electrons are pushed inside the rod. … Radio waves are modulated radiation with photons from infrared to gamma and by this they are technically part of the EM spectrum, but in a strong physical understanding, they should not. …

When a particle has been shifted forward, why will it even come back and vibrate around it's initial position. You are inhibited in your reflections by the example of air. Instead, take a metal rod …

Radio waves are generated by synchronously and periodically accelerated electrons and the periodic impact of polarised photons on a receiver can be measured. Here one can speak of an EM wave. …

Let me explain the nearfield phase shift of π/2 by how an antenna work. The antenna is an open electrical "circuit" where a electrical generator push and pull electrons inside the antenna rod. And the …

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 …

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

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. …
