Do all waves use the same formula share and the same principles?

In summary: Some equations, such as the wave equation mentioned, pop up again and again. In summary, the conversation is discussing the use of advanced technology in the Signature TITAN speaker, and the possibility of using the same formula to design both radar and speakers. The participants also touch on the behavior of radio/microwaves and audio waves, and the high prices of certain audio equipment.

trying to figure out what they mean by this statement.

The Signature TITAN employs technology derived from advanced tactical fighter plane design, nuclear reactor containment construction and atomic submarine radar jamming.

do radio/microwaves and audio waves behave the same way? can the formula used to design radar be used to design a speaker?

Well, there's wave equation,

[itex]{ \partial^2 u \over \partial t^2 } = c^2 \nabla^2 u [/itex]

(time variable t, spatial variables x1, x2, …, xn, scalar function u = u (x1, x2, …, xn; t))

The solutions to this PDE behave as waves do. c is associated with the propagation speed of the wave. Unique solutions are obtained by setting more conditions, like the initial state of the wave, or boundary conditions. This equation occurs almost everywhere there are waves.

The OP didn't way where the quote came from, but Google found it:
http://www.moonaudio.com/titan_spkr.htm

And from the same site at http://www.moonaudio.com/shelf1.htm:

Far superior to cones, pucks, rubber, wood, metals or other insulators ... air provides zero transmission of the acoustic energy into your device..

These guys design speakers, and they don't think air transmits acoustic energy?
Oh, purlease... :rofl::rofl::rofl::rofl::rofl::rofl::rofl::rofl:

High end audio is full of people with more money than sense. If they can sell speaker systems for $0.5m to idiots, good luck to them IMO.

I see they are also selling 3 feet of wire at a recommended retail price of $4800. What's it made of, solid gold or something? http://www.higherfi.com/cables/1 [Broken]

Oh man, I didn't read the link before I posted the above. How awful.

thx for the replies. they sold a pair of speakers for $2 million.

do radio/microwaves and audio waves behave the same way?

Depends what you mean by "behave"...generally the answer is no.

For example, audio sound waves are require a medium ...like air...some compressible medium...and cannot be transmitted in a vacuum, like outer space, are relatively slow. Microwaves need no medium and travel close to 'c'. Their frequency range definitions are also different...although that doesn't necessarily mean different behavior in itself.

Generally speaking, different kinds of waves have different underlying principles and therefore have different governing equations (not necessarily the "wave equation"!)

Many of the analysis techniques, however, find general application across kinds of waves.
 

1. What is the formula for all waves?

The formula for all waves is the same, which is v = fλ, where v is the wave velocity, f is the frequency, and λ is the wavelength.

2. Do all waves follow the same principles?

Yes, all waves follow the same basic principles. These include reflection, refraction, diffraction, and interference.

3. Are there any exceptions to the formula for waves?

There are some specialized wave phenomena, such as quantum waves, that may have different formulas. However, for most common types of waves, the formula v = fλ applies.

4. Can the same formula be used for both mechanical and electromagnetic waves?

Yes, the formula v = fλ can be used for both mechanical and electromagnetic waves. However, the values of v, f, and λ may have different meanings for each type of wave.

5. How is the wave velocity calculated using the formula?

The wave velocity is calculated by multiplying the frequency (f) by the wavelength (λ). This value represents the speed at which the wave is traveling through a medium.
