Hello dear readers of negarinfo , Let’s jump in the subject “which of the following is an example of a medium that does not transmit a wave?” .

Hope you enjoy the article. Thanks for being with us to the end.

 

Which wave never needs a medium?

Electromagnetic waves do not require any medium to travel. Electromagnetic waves include radio waves, light waves, x-rays including the waves transmitted by satellite signals from space.

A wild unmanned spacecraft once sent into our galaxy continued to transmit radio signals received at NASA base station long after getting to the edge of our galaxy- the milky way. The spectacular observation was that the signals were received 8 minutes after it was transmitted from the satellite.

If the speed of electromagnetic signal is 300,000,000 m/s and it takes 8 minutes for the signal to reach the ground receiver, how far has it travelled away from the station? 300,000,000 x 8 x 60 = 1,440,000,000,000 meters.

It has continued the journey and may have crossed into other galaxies. As if to add fun to the journey, the scientists inscribed a male and female image, added the spatial position of our galaxy and which planet they were coming from. I read that article from the hardcopy of a scientific magazine and I have been searching for it online. i think that spacecraft was launched sometime in the 70’s or there about.

Which of the following is not a medium for waves to travel through?

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

What is not a medium in waves?

Electromagnetic waves travel without a medium. … Water and sound waves are mechanical and require a medium in order to travel. Light and radio waves are not mechanical but rather electromagnetic and do not need a medium.

No.

Wave by definition means disturbances in a medium. Wave without medium is oxymoronic and irrational. It’s like saying shadow without a light.

Too much indulging in pure mathematical fantasy disconnected scientists from physical reality. Hence the confusion.

Maxwell explained this nicely.

In several parts of this treatise an attempt has been made to explain electromagnetic phenomena by means of mechanical action transmitted from one body to another by means of a medium occupying the space between them. We have now to show that the properties of the electromagnetic medium are identical with those of the luminiferous medium.

To fill all the space with a new medium whenever any new phenomenon is to be explained is by no mean philosophical, but if the study of to different branches of science has independently suggested the idea of a medium, and if the properties which must be attributed to the medium in order to account for electromagnetic phenomena are of the same kind as those which we attribute to the luminiferous medium in order to account for the phenomena of light, the evidence for the physical existence of the medium will be considerable straighten.

All electromagnetic theories are fabricated by assuming a medium aether exists, and that became the foundation for all our modern electrical and electronics technologies.

What is a light or electromagnetic wave a wave IN? The fluctuation of what medium is a light wave? The fluctuation of what medium is an electromagnetic wave?

when you ask what an electromagnetic wave is a wave in, you’re coming at this thinking that a wave should involve a material medium physically moving in an oscillatory fashion. That is what’s happening in an ocean wave or a sound wave.

But it’s possible to generalize this idea. Electromagnetic waves belong to this more generalized definition of waves.

This is how you can look at it. When there’s a sound wave, it’s true that air molecules are moving. But mathematically, we model this by considering the pressure in the air as a function of space and time. Over time, the pressure in the air oscillates, like a sine function, or something like that.. It also oscillates in space in a similar way. When a transverse wave travels down a string—or say a jump rope—we model it in terms of the displacement of each small segment of the string. Over time, the vertical displacement of a small segment of the string oscillates, as it moves up and down. It also oscillates with space, as some segments at a given time are at crests and others are at troughs, while still others are at nodes.

So a wave occurs when some physical variable that depends on both space and time—like say pressure or displacement—oscillates in space and time. It doesn’t matter whether or not there is a material medium that’s moving. In the case of electromagnetic waves, that variable is either the electric field or the magnetic field (depending on which one you care about—usually the electric field).

Another way of saying this is that a wave is a physical phenomenon that can be described by a function that satisfies a wave equation. For example, the electromagnetic wave equation is
2Et2c22E=∂2E∂t2−c2∇2E=0
where cc is the speed of light. What wave equations have in common is that they are second order partial differential equations in both time and space, with the second derivative w.r.t. time having one sign and the second derivatives w.r.t. space having the opposite sign. (Note: There can be exceptions when complex numbers are involved; for example, the Schrödinger equation.) When a function satisfies a wave equation, its behaviour in space and time will be wavelike. If you have a physical observable that satisfies a wave equation, then the oscillation of that observable is referred to as a wave. That’s how waves are defined and understood in modern physics.
