An atom of oxygen can be suspended in air, yes? Can a wave be suspended independently? Or does it need to be generated?
Independently of what? You can have a hypothetical wave that exists purely in Maths but any Physical wave has to be in the form of some variations of a quantity and that quantity needs to be measurable and 'there'. If you can't measure or detect it then it doesn't exist.Can a wave be suspended independently?
This is mined territory! I want to remind participants (in advance) that we don't debate philosophical questions, the more as we already have plenty of threads, in which the question about the connection between "existence" and "measurement", resp. "observation" is discussed. Our search engine will be of help to all who are interested in following this path.Gravitational Waves have only recently been shown to exist. Before some valid detection was achieved, they only 'existed' in our theories.
Why do you ask only about the radio wave in the atmosphere? Why not in space? What do you thing the answer is for a radio wave in space?A wave has to travel, yes? From one point to another? In its travelling, say a radio wave through the atmosphere, is it wrong to think of the wave as suspended?
I did not have a reason for framing the question as I did. It was an example only. My understanding of waves and space is elementary. Perhaps you can fill me in. What are all the places where waves (quantum waves?) occur?Why do you ask only about the radio wave in the atmosphere? Why not in space? What do you think the answer is for a radio wave in space?
Regarding the atom part, I am now confused about what are you asking. Atoms can be manipulated and isolated. Initially I thought you read about these atom traps where atoms are slowed down or even at rest for some time. But these experiments are done in high vacuum so if the atom can be considered suspended, it is not in air. Unless you man the "in air" as a figurative way of saying "in space".nasu,
But, perhaps you can tell me, what it is to be an atom of oxygen in air, or water, or wherever else it appears. What can physics say for certainty about its properties besides what I have read, that it has mass, charge and spin? The atom is 'somewhere' in the air I breathe. Can it be isolated from other atoms in air?

I don't know, that is why I ask.
What would it be suspended in? One thing about all waves is that energy is being transported. Even in a standing wave, energy can be thought of as moving leftwards and rightwards, to produce stationary peaks and nulls in the energy distribution.is it wrong to think of the wave as suspended?
